iTunes 12.7 removes ability to save .ipa files to PC

In what I imagine is a continuing push toward greater control over the apps running on iOS devices, hopefully in the name of security as opposed to inconvenience to users, Apple has removed the ability to save .ipa files (which correspond to apps) onto one's PC (or Mac, presumably) starting from iTunes 12.7 (Apple removed the App Store from within iTunes). If you value that capability, you will probably not want to upgrade your iTunes software if you still have a pre-12.7 version.

For loading .ipa files onto iOS devices, I have generally switched to using CopyTrans (not iTunes), as I wrote here. However, ever since iOS 9 (per ), the only way to get those .ipa files was through PC iTunes. iOS 9 removed the ability to transfer .ipa files onto a pc from apps already loaded onto an iOS device.

I have periodically had a need or desire to load an earlier version of an app, when some aspect of the current version wasn't working the way I wanted. Less than a month ago I so reverted Opera Mini to the earlier version 14, since the new version (16) forcibly includes a bunch of mass-market web articles, which I don't want. (Reverting conveniently fixed a space-rendering problem when viewing various websites [though notably not Google News], a problem which started perhaps a few months earlier, and which I'm guessing was due to some Opera Mini data corruption on my iPod.)

I don't think Apple is likely to ever reverse this change, so I'll be staying away from iTunes 12.7 and its successors as long as possible.

9/21/17: Apple still provides access to pre-12.7 iTunes installers for Windows (search for "itunes" on https://support.apple.com/), but that could change at any time:

• iTunes 12.1.3 for Windows (32 bit)
• iTunes 12.1.3 for Windows (64-bit)

10/7/17:

• If you deinstall a 12.7 (or later) version of iTunes, and replace it with a pre-12.7 version:
• You may have to sacrifice the data in your My Music\iTunes\iTunes Library.itl file because the earlier version of iTunes may not (probably won't) work with one that has been modified by a 12.7 or later version of iTunes. How much that file's contents matters to you depends on how you use iTunes. You may be less dependent on it if you use third-party software (e.g., CopyTrans, which I wrote about here) to manage iOS device(s).
• You will want to avoid upgrading it when you get apparently periodic prompts to do so from the Apple Software Update software. I don't think there is a setting via which it would automatically upgrade to a newer version without prompting for your approval, but if there is, you will want to disable it. 
• Depending on the model of your iOS device(s) and/or iOS version(s), a certain version (or higher) of iTunes will be needed to manage it. If you had 2 (or more) PCs, you could manage your device with a 12.7 or newer version of iTunes on one PC, and use a pre-12.7 version on a different PC to download .ipa files.

Apps useful for my trip to London

Recently I traveled to London. I am not much of a photographer, neither in frequency of shots taken, nor, as many will rightly say, in quality of shots, but having the 4th generation iPod Touch with its camera led me to take some shots, like this one of the Big Ben Clock Tower.

In preparation for the trip, I created a (free) Google Voice account which would be able to call U.S. (and Canada, I believe) numbers for free until the end of 2012 (I believe that was extended from its original end of 2011 cut-off date) 2013 (http://gmailblog.blogspot.com/2012/12/free-calling-within-us-and-canada.html). A knowledgeable friend had advised me that such an account could be used by the (free) Talkatone app to turn the iPod into a phone (1/3/14: That capability is ending on 5/5/14 due to changes by Google; see, for instance, the 10/31/13 post on https://www.facebook.com/talkatone.). I installed Talkatone, and despite a few hiccups during stateside testing, it worked quite well from London, allowing me to retrieve some messages from my answering machine. After returning from London I did a little more testing and, on one occasion, I was surprised that I could call a landline but could not reach a cell phone. Anyway, the combination of these two things served me well across the pond, even if the sound quality is not great.

I loaded up some additional free apps for the trip, listed below in approximate order of usefulness. Some of them would have been more useful, except I had alternate, more helpful, resources, which I will also mention.

• London: Travel Guide - Time Out has assorted information about London.  I did browse this a bit, but it was of minimal use to me because I had the good luck to borrow from the library the (more useful) 2010 Kindle e-book of Time Out London, which I consulted instead.  I also had several similarly recent, printed London travel materials on loan from a friend.
• Brighton Museums was good for £1 off entry to the Royal Pavilion in Brighton (about an hour by train from London).  It has photos and brief information about the Royal Pavilion and other attractions, but its primary benefit to me was the discount.
• Tube Map has, in addition to a map of the London Underground ("the Tube"), a Lines button which shows up-to-date information by subway line, e.g., "Good service", "Planned closure", "Part closure", "Line issue" (all of which I am seeing as I write this entry).  A small popup window may show periodically on the map with Tube alert-type information; I'm not sure if that overlaps with the Lines information.  The Tube Map app's buttons, advertising, and alerts naturally take up part of the iPod's precious screen space.  With hindsight I should have checked the Lines status each day before leaving the hotel (or leaving anywhere else I had WiFi), but I did not run into any meaningful Tube schedule disruptions (and at various stations I did learn in person of some minor scheduled service changes which were part of preparation for the coming Summer Olympics).  I had also loaded a PDF of the London Tube map (which I'd found using Google) onto the Dropbox app and saved it as a Favorite therein so that it would be available without WiFi access.  That was my real Tube resource, and was extremely useful both for scoping out trips in advance and while on a train.  In the most extreme situations, when riding with only one hand free, it was still easy to use spread-to-zoom and swipe motions to confirm that I was on the proper train, which easily beat doing so using a clumsy folding map with tiny print.
  (3/21/12: With their 4.1 update, the makers of this app have added integration with their Bus London app, of which I just learned, and could have been handy for the Tate Britain museum, which is a bit of a walk from the nearest Tube station. Supposedly within the Tube Map app, you can now find bus departures around a Tube station.)
• Hidden London contains photos and information about some less well-known attractions.  Although I had mentally noted some of those attractions before the trip, in the end it was only by accident that I happened to walk by one (the Cartoon Museum) and actually went to one (the Cafe at Tate Britain).  Regarding the latter, I had gotten confused about museums and went to the Tate Britain instead of the Tate Modern, but as this app notes, this "little know[n] excellent cafe hides in the basement of this grand art gallery.  Open daily, the cafe serves amazing cakes, snacks and a range of tea and coffee."  The cafe truly was excellent!
• ExCel London provides some general information, including food availability, about the convention site, which would presumably only be of interest if you are attending an event there.
• i-Shop has some information about possible discounts or tax refunds from selected shops.  I did see the Global Blue symbol (Global Blue is either the producer or somehow related to this app) inside the Tower of London gift shop, but I did not buy enough stuff to make serious investigation of this app worthwhile.

In addition to the Time Out London e-book mentioned above, I also borrowed a recreational reading e-book from the library before the trip.  Library e-books "return" themselves, so you never need to worry about them (unlike the half-read physical book which I had to return to the library on my last night in the U.S. during last minute trip preparations!).  I also bought an e-book for the Kindle app, so was well stocked with reading material.

The Notespark app, which I originally wrote about here, facilitated organizing London topics and a daily schedule.  I used a particular Tag for all London notes, and starred all of those notes.  Most of the time I would just work with the group of Starred notes.  I also dedicated a single note for each day's potential agenda, an agenda which often went through revisions.  When the contents of any note were no longer relevant for the remaining days of my trip (although I expected to revisit all London notes after the trip), I unstarred that note so that it would no longer be visual clutter.  I could use Notespark to search through whichever group of notes was more relevant, the Starred ones, or the group associated with the Tag which I used for this London trip.

When I had WiFi access both before and during the trip, I saved static copies of a number of London-related web pages, e.g., for various tourist attractions and travel tips, using the Opera Mini browser (about which I wrote most recently here).  I'll admit that despite getting a bunch of information in advance about Oyster Cards and Travel Cards (both of which are options, pointedly not mutually exclusive, for using the Tube and some other transportation systems), it wasn't until pretty late in the trip that I felt I really got a fuller understanding of them.

iPod: from 3rd to 4th generation under iOS 5.0.1

A while back, my 3rd generation iPod crashed so hard under iOS 4.3.5 that it "lost its mind". I used PC iTunes 10.5.0.142 to load iOS 5.0.1 onto its wiped-clean "mind", but its longstanding port hardware problem soon thereafter became so serious that I could no longer charge it without precariously holding the cable just right (for the entire charging period, something I wasn't about to do).

I got a 4th generation iPod which was initially at iOS 4.3.3, and got errors when trying to reload it with iOS 5.0.1. The Apple error message's first recommendation was to update PC iTunes, which I did, bringing it to 10.5.1. It seems logical enough that Apple might require the latest version of iTunes for such operations. I was then able to bring the iPod up to iOS 5.0.1.

In PC iTunes, I then attempted to Restore from Backup. There were two backups, one from my initial activation of the 4th generation device (and therefore not useful), and another of the 3rd generation one from 6 days earlier. Attempts to restore from the second (chronologically earlier) backup failed, reporting that the backup session failed.

More recently I had been doing backups to iCloud, and two of those backups were there. The first had virtually no data from my activation of the new iPod minutes earlier and was therefore not of interest. The earlier one was from 2 days earlier (from the 3rd generation iPod), and I began restoring from that. Ah, the beauty of the iOS 5 backup over WiFi, which takes place when you are charging at an outlet. You always have to charge; backup is a perfect thing to occur alongside.

The iPod reported that some items could not be downloaded, but that I could restore them if I had them on my (PC) iTunes by doing a sync operation. The following apps were not restored from the iCloud backup because they were no longer available in the App Store (Could there be any other reason why an app wouldn't have been restored?), but I still had them in my PC iTunes:

• CED
• Go To There
• InstaPaper Free

My outgoing 3rd generation iPod still had some battery charge (I had been conserving the remaining charge with Airplane Mode, turning it off, turning the brightness down all the way), so I could visually compare if any other apps were missing after the PC iTunes sync.

PC iTunes lists the device, presumably purely cosmetically, as a 3rd generation iPod.

I did a certain amount of work resetting app configurations and restoring data from servers associated with the apps.

Assorted impressions of the 4th generation iPod:

• Great to have cameras. I had recently been at the scene of an accident with my camera-less 3rd generation iPod, and stayed as one of the witnesses for the police who eventually came. If I had had this back then, I would have snapped pictures which would clearly have shown the policeman that the errant driver was in the wrong lane at the time of the accident. Fortunately I believe enough witnesses corroborated that anyway. You can also use the front-facing camera to use the iPod as a pseudo-mirror.
• The addition of a microphone changed (downgraded) what Apple included as earphones (my blog entry).
• The power button was moved to a more awkward position away from the top edge, making turning it on/off and taking screenshots (press power button + home button) clumsier. Maybe the new placement was needed because of the cameras or other hardware issues.
• Volume buttons were similarly moved to a more awkward position away from the side edge.
• The 3rd generation iPod's screen always looked great to me, but the Retina display of the 4th generation iPod is even sharper. My Opera Mini browser's saved Speed Dial images looked worse than they had on the old iPod, but simply recreating them fixed that. I had the initial impression that I needed the screen brightness to be slightly higher for the new iPod than for the old, but I'm no longer sure about that.

Opera Mini vs iOS 5 Safari

This entry is originally being written to compare Opera Mini 6.5.1 (1/16/12: I upgraded to 6.5.2 and have noticed no problems with it.) with iOS 5.0.1 Safari, primarily on an iPod, although some non-iPod comments may be included.  This entry will likely get updates, either unadvertised or advertised-with-dates, over time.  I mostly read text while browsing the web on my iPod, which is probably one reason why Opera Mini works so well for me.  I have little to say about images and videos in Opera Mini.

My earlier blog entry about Opera Mini 6/6.0.1 vs iOS 4 Safari.

The free Opera Mini web browser is an alternative to Apple's Safari browser, with various pluses and minuses. Wikipedia has a decent article on it: http://en.wikipedia.org/wiki/Opera_mini, which also links to the interesting http://dev.opera.com/articles/view/opera-mini-web-content-authoring-guidelines/. A list of technical specifications can be found at: www.opera.com/mobile/specs/.  Version 6.5.1 was released on 11/14/11, with some fixes for 6.5, which was released a little while earlier.  Version 6.5.2 was released 1/11/12.

Opera Mini has long been my primary browser for my iPod (and later, iPad, too).  An iPod is typically connected to the Internet less often than an iPhone, so some of the following items (e.g., Saved Pages) are more significant for iPod users like myself.

PROS:

• Opera Mini does not automatically reload a page when you tap the back arrow to return to it, at least if you return within "some" period of time (about whose duration I cannot be more specific).  Thus, if you are reading a page which has multiple links to other pages, e.g., Google News, then tap to read an article, returning to the original page will often not invoke (frequently pointless and time-wasting) reloading, unlike in Safari. Also, if you load pages into different tabs while you have Internet access, but later lose that access, you can sometimes still read those pages, even without having stored them as Saved Pages. If you switch back to or restart Opera Mini, it does not attempt to reload pages fresh from the Internet; if it still "remembers" them (which apparently is not always), it gives you back what it last had for their content. Interestingly, Google News now seems to reload on rare occasions, which I do not remember happening previously; that could be because of changes in Opera Mini and/or at Google News.  Available RAM issues mentioned below may still be applicable.
• Unlike in Safari, you don't have to switch away from the current tab to open new pages, because you can open links in background tabs (tap-hold, then tap on "Open in New Tab"). This is helpful while, e.g., reading through all headlines in Google News, allowing you to open all stories you'd like to read in background tabs. Available RAM issues mentioned below may still be applicable.
• Unlike Safari, Opera Mini allows saving of static copies of web pages on the iPod, letting you read or reread them later even without wireless Internet access. That can be useful to save pages for recipes, technical reference, humorous articles, or for any other reason, e.g., because you don't have time to read them right away.  Safari's Reading List saves URLs (across all iOS devices sharing the same Apple ID), but still requires an Internet connection to view those pages.
• At least 15 (someone else can test for the maximum number...) tabs are possible in Opera Mini, exceeding Safari's limit of 8. RAM constrains the total number of tabs effectively usable. "The page has been cleared to save memory." message is what you are left with content-wise on a tab when you run low on available RAM.
• Using Single Column View ensures that, because of its size, text will be pleasantly readable in portrait mode, at least for me. http://www.thechessmind.net/ is a chess blog which I often read. In Safari, I normally need to "spread" or switch to landscape mode to make the text more legible, but the text has always been fine to read right away in portrait mode in Opera Mini.
• If you make an account on Opera's servers, you can use Opera Link to determine at what frequency to save both your (up to 9) Speed Dial targets and your bookmarks there, for future restore (e.g., in case of a serious crash) or for sharing on another device(s), including on a pc.  Automatic syncing is possible, but I prefer to sync bookmarks manually, which avoids attempts to connect to Opera's servers when you know (or perhaps, even when you don't know) that you lack wireless Internet access.  Opera Link can also be used at any time on any Opera Mini instance device, so it is not linked inextricably to an Apple ID like iOS 5 Safari's Reading List. Although I didn't test this, it appears that if you use desktop Opera, there is supposedly an Opera Mini folder for bookmarks, which is the extent of the bookmarks that get synced with Opera Link.
• The location box now has a star which is a shortcut to bookmark a URL; this portion of the star's functionality is actually only achieving parity with Safari.  You can also still bookmark a URL the older, slower, but more functional way as well.  The star's bonus is that if you are viewing a previously-bookmarked page, the star is yellow, indicating its already-bookmarked status.  This can help you avoid unintentional duplicate bookmarks, though maybe you'd want to bookmark a URL in more than one bookmark folder. A drawback of using the star shortcut to bookmark a URL is that you do not have the option of using something other than the web page's HTML title as the bookmark's title.  One news site that I frequently use often doesn't include useful page titles, so I would want to edit in something useful if I were to bookmark such a page.  Since bookmark names are limited to less than the width of the iPod screen, I also might want to edit out words with no real identifying value from some page titles when creating a Bookmarks -- I need to be able to identify each by the short text.
• After being forcibly ejected from RAM (by the user), Opera Mini starts up with the page data it previously had.  This does mean, however, that you cannot close multiple tabs at once, which I consider a favorable trade in functionality.
• Opera Mini's x cancel button is bigger than Safari's, and is spaced farther away from other things you wouldn't want to hit. Better for those times when you've inadvertently tapped on a link which is still loading, but in whose content you actually have no interest.

CONS:

• Opera Mini does not provide end-to-end encryption. If you want to avoid putting your sensitive data in their company's hands, don't use Opera Mini for anything requiring credentials or anything to which you're concerned about them having potential access. (I blogged this using Safari on my iPad, and made subsequent small edits using Safari on my iPod.)
• There is a short startup delay as it makes the connection to the Opera proxy servers ("calls home"), and apparently also retrieves your local settings.
• Presumably because of the Opera proxy server, has extreme difficulties using maps.google.com effectively; I strongly advise using Safari for that. Even Safari cannot yield copyable text, though.
• On rare occasions, my initial attempt to bring up a page doesn't succeed, which I imagine is an Opera proxy server issue.
• Opera's proxy servers may lead to this side effect:
  Going to, e.g.:
  http://www.cnn.com/2011/HEALTH/05/26/dumb.doctors.office.ep/
  prompts you with:
  It looks like you are from outside the U.S. Would you like to make International your default edition? Yes | No Close
  which I chose to simply ignore.
• Records of chess games using figurine notation in ChessBase website articles like http://www.chessbase.com/newsdetail.asp?newsid=7882 are not, for all practical purposes, readable in Opera Mini, which does not render figurine notation properly.  For this particular game, Alejandro Ramirez the annotator apparently used (non-figurine) algebraic notation for his handwritten notes, but copied and pasted in figurine notation from complementary analysis generated by a computer chess program.

OTHER OBSERVATIONS:

• Only Safari can Add to Home Screen, using apple-touch-icon.png  when available (not favicon.ico, as it turns out; according to http://www.webmasterworld.com/html/3560399.htm).  Opera Mini's Speed Dial is a substitute, which I actually find more helpful because all 9 are in the same place.  If you were to bookmark multiple pages in Safari, that would create additional icons on your Home Screen which are less likely to all be in the same location.
• When using Single Column View, some items which might typically (as viewed, e.g., while not using Single Column View, or in Safari) be unobstrusive on the side of a web page may appear, sometimes as a large clump, at the top or bottom. I have gotten used to that, and simply swipe to get past the clump, if it's at the top, to get to the real content, e.g., on http://www.thechessmind.net/. This conveniently means that I typically don't even have to see any advertising which ends up in a bottom clump.
• Find in Page: The Done button means done with searching; search happens as you type. Can search repeatedly in a page. Safari can find in page also, although it's probably somewhat less intuitive; see, e.g.: http://www.tipb.com/2010/09/16/ios-42-features-find-text-safari-web-page/
• If a tab's pages started from the Start Page, you can return directly to the Start Page (the first page viewed in that tab) by tapping the O ("Opera") button, then tapping Start Page. If a tab's pages never included the Start Page (because the tab was created with "Open in New Tab"), there is no access to it within that tab.
• 9/4/11: Power-User settings are available by going to config: in the location bar, as described further on http://www.guruslodge.com/bmobile-phones-tutorial-and-solution-centerb/operamini-secret-codes/, which I just discovered. Changes likely survive Opera Mini crashes. For my own usage, I turned off the Phonenumber detection, which I suspect is probably only of use if (a) you have an iPhone (which I don't), and want to call such a number immediately, or (b) you normally use iOS assistance to add new contacts (which I don't, for reasons mentioned here).
• On an iPad under iOS 5.0.1, I updated Opera Mini 6.0.1 to 6.5.1 on two separate occasions (I reverted to 6.0.1 after the first time), but could no longer save pages.  In between those two attempts, I was surprised to see 6.5.1 successfully save pages on an iPod running iOS 5.0.1.  I decided to sacrifice my iPad's Opera Mini saved pages, delete the 6.0.1 entirely, and download a fresh Opera Mini 6.5.1 (3rd installation), which allowed me to save pages.
• Opera Mini's Single Column View trumps Safari's Reader, in my opinion.  Particularly on the iPod, why wait to have something drawn (or partially drawn) before you can activate Reader, when all the while you can see that the text will be too small to read (without the Reader enhancement)?  Just go directly to the readable version, all the time, with Opera Mini's Single Column View.  I once saw a page with ads in the middle of the article and the Reader rendition ended at the ad.  I can't reproduce that now with the same page, but regardless, I prefer to maximize my chances of getting all the text the first time, legibly, as fast as possible.  Safari's Reader remains helpful any time you are in Safari and are confronted with too-small-to-read text, e.g., when clicking on a link in e-mail, which will open in Safari (unless you have jail broken your iPod to configure a different default browser, which I think is possible).
• When using tap-hold ("Long-click" in the Opera Mini help) to select text, Opera Mini selects the word closest to your position and displays a beginning and end marker, each of which you can drag to change the text selected.  When done, you tap Select and choose from Copy/Search/Search With...(and Go to Address... if the selection is a single word).  As far as I have been able to tell, Safari does the same kind of initial selection in mobile sites, but the choice (no need to tap an additional Select) is Copy (and Define if the selection is a single word).  For non-mobile sites, Safari selects the paragraph closest to your position and displays 4 markers (top, bottom, left, right) which you can drag to change the text selected.  I'm not sure if I've ever needed to do anything but Copy after selecting text; if I do, I'll try to add that detail.  Opera Mini may also behave differently when not using Single Column View, but that is left as an exercise for the reader; I always use Single Column View.
• The Single Column View option no longer exists under Settings on the iPad, if it was actually there in earlier versions, which I can no longer remember.

Update an app but retain option to revert to older version

Data you save for an app might not be able to be restored (it really depends on how the app stores data) if you restore the app using this technique.  If that data is valuable enough, you may be obliged to never revert from the update of such an app.  Your need to continue using your already-saved data may force you to accept any changes in behavior of an app's new version, even if you could revert the app itself.

The following steps using PC iTunes over USB cable enabled me to revert to Opera Mini browser 6.0.1 after a quick, disappointing test of 6.5.1 on an iPad running iOS 5.0.1, and should work the same way on an iPod.

The following presumes the iOS device is normally using iCloud backup, and also that Opera Link was previously used to save bookmarks and Speed Dial targets.  Other apps may have other customization steps akin to Opera Link.

• Disable backup to iCloud on device (I overlooked this precautionary step in my test).
• Disable backup to iCloud on device within PC iTunes (if needed).
• Backup device via USB cable to PC iTunes.
• Update app on iOS device over wireless.
• Test updated app on iOS device.
  12/7/11:  If you are going to test the app for an extended time, DO NOT leave the app on the device when syncing the device with PC iTunes before completing testing, because the sync will wipe out your old version of the app in PC iTunes.  If you are saving any data with the new version of the app, you're going to have to give it all up should you need to delete the app for this scenario.  I overlooked this when I was testing 6.5.1 on my iPod, so I lost my 6.0.1 version in PC iTunes, but fortunately 6.5.1 turned out to be a superior replacement.
• If you prefer the older version of your app, delete the updated app from iOS device, then manually copy the older version back to the iOS device within PC iTunes.
• Use Opera Link to restore bookmarks and Speed Dial targets (the latter will get up-to-date page images).
• Disable Opera Link (unless you normally keep it enabled).
• Move the (restored) Opera Mini icon to your desired Home Screen location.
• Re-enable backup to iCloud on device.
• Re-enable backup to iCloud on device within PC iTunes if needed.

Remember that PC iTunes can save (specific versions of) apps even if they later get removed from the App Store.  Some apps are removed because they are replaced by a newer version, and some get totally removed (often enough without explanation).  I haven't tested, but something like the above likely works from iCloud backup, except perhaps for apps removed from the App Store.

6/25/12: The following (or something close to it) is behavior I observed a while back during testing, which is quite logical but caught me by surprise:
If you have multiple iOS devices syncing with the same PC's iTunes, be careful with any app which is a Universal Binary (same app runs on both iPod/iPhone and iPad size screens, making full usage of the two respective screen sizes) which you use on all devices. If you update it on one device and sync that device with the PC's iTunes, the other device(s) will also get that app updated to the newer version when it syncs with that PC's iTunes.

iOS third party apps you may not wish to update

(Last updated, in whole or in part, on 10/28/13, when I was using iOS 5.1.1. Intended to be updated over time.)

Newer versions of apps sometimes function worse than their predecessors. Sometimes existing functionality is taken away or is changed in an undesirable way (sometimes breaking entirely).

Below are apps for which I consider or have reason (e.g., App Store reviews) to suspect that a non-current version(s) worked better. Having been burned in the past, in the App Store app's Updates section I long ago stopped using the Update All button in favor of updating apps individually. If this list grows too large for me to remember easily, it will be handy for me to check against when updating apps, to reduce the chance of updating an app for which I prefer an older version.

If an older version of an app works well, and there is no compelling or interesting new functionality offered in its newer version(s), I would not likely bother with much testing of newer versions. If someone using a newer version of any app listed below finds my comments about functionality to be incorrect, I would welcome a comment to that effect, which could prompt me to do additional testing and potentially revise this list.

If you made a backup of the iOS device to PC iTunes before updating an app on the iOS device, deleting the new version of the app (e.g., if you don't like it) from the iOS device, then using PC iTunes you should be able to get the older version back via either direct copy or sync (my Opera Mini 6.5.1 test on an iPad). If you don't take such precautions, you could be locked into the new version.  (10/28/13: http://www.iphonehacks.com/2013/07/revert-to-older-version-ios-app-itunes.html has good information, and you can do a Google search for "recover old ios app .ipa", which is how I found that web page.)

I haven't investigated to what degree iCloud backup can be similarly helpful (as PC iTunes) for such things, but my understanding is that if the App Store no longer has an app, you will not be able to get it back from there. I have several free apps which are no longer in the App Store, but which I can still restore to my iOS devices from PC iTunes, including:

• CEDictionary 1.0 (Chinese English dictionary which speaks pronunciation)
• Go To There 1.1 (retrieves and formats public transportation information)

iOS 5:

• Convert Units for Free - #1 Unit Conversion App 4.0. Version 4.1 was released 2/28/12, and the 5 "Most Helpful" reviews are all 1 star out of 5. Based on the content of those reviews, ads have proliferated wildly in the app. 14 of the 31 ratings are 1-star, outgunning the 11 that are 5-star. If those reviews are on the mark, its advertised "#1 Unit Conversion App" status is likely in jeopardy (if that was accurate in the first place, of course).
• Flashlight (my blog entry) 5.1 This is the app from John Haney Software, which became Apps from Outer Space when 5.2 was released. 5.2 seems to have a slightly longer delay before the flashlight effect, which is a net negative since I want bright light as soon as possible. I expect I'd still choose 5.2 over other flashlight apps, but I plan to stick with my 5.1.
• Google Search 2.5.2 Version 3.0.0, released 4/29/13, "[n]ow turns on Location Services. Even though the icon stays on, the app has minimal battery impact." While the calmer reviews in the Apple App Store seem to agree, the ones decrying the truth of that make me a bit leery of upgrading.
• How to Tie a Tie Free 4.0 Some App Store reviews suggest that version 4.1 may now hammer you frequently to rate it, and provides a pre-written 5-star review for you to approve. No, I haven't rated it, but I also haven't truly used it to tie a tie, either, despite having loaded it quite some months ago, and only ever knowing one lame-looking knot. I don't need to be browbeaten to rate this app.
• Mercury Web Browser Lite (my blog entry) 5.1 didn't show ads on the iPod.
  5.2 does show ads, though not continuously. I would probably not have upgraded, but I was dealing with a version problem with a different app when I synced with PC iTunes, and I hadn't paid enough attention to this app, which I use relatively rarely.
  5.2.1: The company's write-up in the App Store says "Remove ads for iPhone version". A review claims that 5.2.1 also took away User Agent spoofing, which can be pretty useful.
  I bought the paid version, which still has the User Agent spoofing. The developers have done good work, certainly worth 99 cents!
• Mercury Web Browser Pro (my related blog entry) 6.0.1 preserves the last used brightness setting into the next session. A review claims that 7.0 starts up at full brightness, which night readers are likely to find undesirable.
• Notespark 1.3.2 Version 1.4 (AND/OR possible changes on their server?) caused loss of data when I synced (I only sync manually) on at least half a dozen occasions in fewer than two months of daily (or practically daily) usage. I count myself very fortunate to have been able to revert back to 1.3.2, and will be watching to see whether I encounter similar loss of data now -- the syncing was virtually flawless for years before I (temporarily) upgraded to 1.4. (10/28/13: Notespark has been removed by the developers from the Apple App Store.)
  
• ShuBook 1.4.2 appears to be markedly preferable to later versions. Some App Store reviews slammed version 2.0.
  
• Speedtest.net (my blog entry) 2.1.1 Some App Store reviews for 2.1.2 and 2.1.3 have made me leery of updating. The app works fine for me already, and supposedly there are some new legal agreement issues. Also, the 11/24/11 App Store review of 2.1.3 from joekul claimed that the history (of WiFi speed test results) feature went missing. I don't have specific plans to verify that; 2.1.1 still has that history, which is of some value to me.
  
• The Weather Channel (my blog entry) 4.1.1 Some App Store reviews for the subsequent version have made me leery of updating. It sounds as if the ads have gotten more and more in your face (flashing, it seems) without meaningful gains in functionality.
• Weather+ Free 1.6 includes forecasting of humidity levels for the coming days (accuracy not guaranteed, of course!). Version 2.0 (updated 6/21/12) no longer has that functionality. That functionality also seems to have disappeared in the paid version 2.02 (also updated 6/21/12), based on what I see in Apple's App Store.
• White Noise 5.4.2 The 5.5.1 update introduced a bug which prevents the alarm from sounding if you are using the Music Alarm Event (through which you select Music from your device's Songs collection to which to wake up). Also, I prefer the fake big LED clock digits of 5.4.2 over the slim digits of 5.5.1. With 5.4.2, I already have all the functionality I need from this app, so there's really no significant utility in updating further (indeed, there is risk, as I discovered with 5.5.1).
• Yahoo! 2.3.8 At least two Apple App Store reviews suggest that in 3.0 (released 4/22/13), they removed Mail from the menu, which I use to mark messages as spam. The Yahoo! Mail app, which they suggest you use instead, requires iOS 6. I'm staying with iOS 5 as long as possible for multiple reasons, one of which is because the accompanying text for podcasts is truncated in iOS 6 (and was initially truncated from the Podcasts app in iOS 5).
  They had previously removed Mail from the menu in version 2.3.7, but with 2.3.8 (released 3/22/13), they restored it due to "popular demand" ("popular outrage" might be more accurate). Given the history, I can't muster any enthusiasm to even bother trying version 3.0.

iOS 4 (I'm only listing a couple of apps and am unlikely to add more, since I'm in the iOS 5 world now):

• OverDrive Media Console (my blog entry) 2.3.2 Version 2.3.3 apparently introduced a bug that prevents download of e-books to the iPod under iOS 4.3.5. It may even wipe out existing e-books, but I cannot confirm that.
  (Version 2.3.3 can, however, download e-books to the iPod under iOS 5.)
  
• Stanza (my blog entry) 3.1 Version 3.2 of Stanza doesn't work under iOS 4.
  (Version 3.2 is needed under iOS 5, which would not run 3.1.)

Crash landing on iOS 5.0.1

I had not been planning to upgrade my 3rd generation iPod from iOS 4.3.5 to iOS 5, having been happy with its capabilities as is.  I had also learned of, and/or experienced, a number of problems associated with iOS 5.  Typically, iOS 5 either broke an existing app, or an app's functionality worsened when the developers updated it to accommodate iOS 5.

I've mentioned on multiple occasions how my iPod has a hardware port problem. Aligning its cord properly to charge can take a few minutes of fiddling, and properly aligning it for a PC iTunes connection is even more demanding.  In those delicate alignment attempts, "Charging is not supported with this accessory" is a message I've periodically seen for more than two months.  That message came up again yesterday as I was trying to get it to charge, and when I tried to lower the brightness...bam, it was totally hosed.  The screen displayed only the iTunes icon and a picture of a USB cord, as shows up when you activate a pre-iOS 5 iPod, which requires a wired connection to Mac/PC iTunes.

After several hours of work, including numerous error messages and laborious re-seating of the cable at multiple junctures, my iPod is now at iOS 5.0.1.  I mistakenly thought that I would be able to restore from my less than two week old PC iTunes backup and remain on iOS 4.3.5.  However, it seems that PC iTunes only allows loading of the most recent iOS version that works for your device -- not unreasonable.  At least I was able to get back my 102 apps from PC iTunes in a single operation.

Backing up to iCloud should reduce my cable alignment problems to only recharging the iPod, since I should be able to restore over wireless from now on.

I was surprised to discover there was no way to mass-reload my hundreds of French language instruction podcasts, but I have started rebuilding my collection manually.  (2/9/11:  Actually, I could have used PC iTunes to copy over all that I had previously synced.)

I was also surprised that my small number of not-particularly-important photos did not come back.  I have seen a few web articles suggesting ways to get them back, and I may yet pursue that.  If I do, I will try to report the result here later.

The Traditional Chinese handwriting recognition seems tangibly slower, both on a 3rd generation and on a 4th generation iPod, than it was on a 3rd generation iPod running iOS 4.3.5.
(12/2/14: When only a single app [Notespark, as a device-local-only scratchpad] is in RAM, the speed of recognition is quite good, possibly similar to the speed under iOS 4.3.5. I'm surprised that I didn't think of testing this approach previously. Of course, it's inconvenient to eject all the other apps from RAM, but in some cases it's worth doing; when I'm done handwriting the Chinese text, I can Select All and copy it elsewhere as desired.)

As I worked to recreate groups of apps and reassemble my desired first Home Screen ("springboard"), I seem to have moved some app icons so quickly that the iOS became confused.  For a while the icons of some random apps (no more than one per screen, I think) became invisible, although their titles remained visible.  With all the icons jiggling and me swiping screens left to right and right to left, the app which was invisible would sometimes change (i.e., an invisible one would become visible, but a different app on the same screen would become invisible instead).  I found it was possible to drag an invisible app onto a visible one to create a group, but not vice versa.  That invisibility problem eventually cleared up, so everything is visible now.

Although Apple tried to disallow moving the new Newsstand app into a folder and off of the first Home Screen, folks have found out how to do that.  I moved it into a folder with Messages and Reminders, two other new apps for which I have no particular need, then moved the folder off the first Home Screen.  A Google search for "ios 5 move newsstand to folder" should find assorted pages with the technique, which does require a certain quickness of action.

Below is a list of some of the functionality which I wanted to recover, and commentary on what was involved.  I tend not to give my location to apps to use, normally entering that manually when I want (e.g., in The Weather Channel app).

1. Calendar (iOS 5.0.1):  I use a Google account for Calendar, so it was simple to add that account to the iPod.  Although the Day and Month views showed my events, the List view was empty at first, so I feared I would have to create another calendar from scratch (ugh) to restore that functionality.  However, the next day the List view showed events normally.
2. Contacts (iOS 5.0.1):  I use a Google account for Contacts, so again, it was simple to add that account to the iPod.
3. Notespark (1.3.2):  All my data is already on Metaspark's webserver, so all I had to do was login and tweak a few settings (e.g., font size, etc.), and I was back to pre-crash functionality.
4. iCED (3.2.3):  I had previously made a Murage account and it was straightforward to download my paid Add-ons again.  I made a few tweaks to settings (e.g., maximize History).
5. tChess Pro (1.7.1):  Much like Notespark, I just had to tweak a few settings to get it to look and behave the way I like it.  I normally e-mail myself the pgn of individual games that I play through using tChess Pro, so I can easily reload those.  I have also kept files on my PC of pgn collections of games, which I can similarly e-mail myself to reload.  (This is one of my most-used apps, so a blog entry on it should eventually appear.)
6. Opera Mini (6.0.1 - pointedly not the latest version, which is 6.5.1, which for now I'm holding off on upgrading to):  Initially I started recreating my Speed Dial locations manually, and had 8 of the total 9 set up -- I didn't know the 9th one's URL.  Then I used Opera Link to restore my (generally-rarely-changed) bookmarks from the last time I saved them, and it loaded the missing 9th Speed Dial location.  Apparently I wasted my time loading the first 8 manually.
7. Safari (iOS 5.0.1):  I was pleased to discover that Apple was apparently already saving bookmarks, so they all came back automatically.  I still prefer Opera Mini, though.  I tend to use Safari only when Opera Mini can't do the job.
   After first writing this Safari blurb, I checked out Safari's new Reader feature, which can render some web pages in a more readable way (hiding ads, too!). In my limited testing, Wikipedia article pages work well with Reader (though http://en.wikipedia.org/wiki/Main_page not so well), as does this eminently readable article about iOS 5 improvements, which is what led me to really test the new Reader and Reading List features. This wiki article about "Kindle Myths and Partial Truths" (some content of which is relevant to iOS devices using the Kindle app) has part of its content cut off on the sides in the Reader view.  I have observed that an advertisement embedded within a column of text on a web page can render Reader results incomplete (on one occasion, none of the article text actually came through in Reader).
   To compensate for the small screen of the iPod, I have long used Opera Mini's Single column view to transform the elements on a web page, including the font(s), into a presentation I find easier to read. Reader fulfills the same function with more polish, but can transform far fewer web pages than Opera Mini.  Without these transformations, text can sometimes be difficult to read without "spreading" pages with your fingers (to enlarge the image), after which you might additionally still need to move the display back and forth to see different parts of the whole text.
   Reading List saves bookmarks to iCloud and shares them in Safari across iOS devices (and Macs, supposedly, too, but I have a PC). The Reading List bookmarks didn't show on my other iOS device in either "direction", initially, and multiple web pages, some from as recently as October 2011, suggested that it didn't work. Perhaps from iOS 5 this syncing was fixed in 5.0.1, because eventually the same Reading List bookmarks showed up on both my iPod and iPad.
   Reading List's syncing seems to be forced among iOS devices sharing an Apple ID. Opera Link's similar syncing of bookmarks is optional, and can be done manually or automatically among Opera Mini instances within which you have logged into Opera Link.
   
8. Kindle (2.8.5):  Login, all my books were under Archived, and it was simple to download 15 of them into Home.  (2 were expired library loans.)  Select a word in any book, then download the dictionary to make it available going forward regardless of Internet access.
9. iBooks (iOS 5.0.1):  Login, go to Store, Purchased, and download each of the 14 (all freebies) again.  Maybe I was doing something in a non-optimal way, but it seemed to be an extremely clunky and user-hostile interface.  I could only download the top 3 books, then had to Swipe to the right to be able to Hide each of them in turn so that I could access the next 3 lower books on the screen.  I had to repeat that procedure to get through all 14.
10. The Weather Channel (4.1.1):  Add my location to Favorites under Bookmarks and get rid of whatever is already there.
11. Dropbox (1.4.6):  Login, mark as Favorites the documents I want saved locally so they're available without wireless Internet access.  Set Local Storage to maximum reasonable for device's capacity.
12. OverDrive (2.3.3):  Although the iPod didn't need an Adobe ID to authorize usage under iOS 4, it requires one under iOS 5.  Download my usual Pitman's Commercial Spanish Grammar to confirm download of public domain ebooks, then test other types (e.g., Adobe ePub from the library) as desired.  (I wrote in another blog entry about how to view Kindle books on library websites using an iPod.)

I am updating this entry with additional items and comments, and am also revising earlier entries accordingly, as time permits.


One of the reasons I started this blog was because I had read Sonny Hung's My Apple Newton (PDA) blog, which he introduces as:

This blog records my Apple Newton experiences, as well as comparisons with other PDAs, Smartphones and Mobile Devices. It is also a repository for storing complex set up procedures for future reference.

I thought I might enjoy doing something similar for the iPod since I found it to be an extremely useful PDA.  Based on the web searches that brought people here, this blog may have been helpful to some other folks, but in any case, it has certainly proven useful to me after this crash.  Given how my iPod seems to be living on borrowed time, my blog will likely serve me well again similarly in the future.

Late Browser Mobile app

8/27/11: I now recommend Mercury Web Browser Lite over the Late Browser Mobile app.

I have not used the free Late Browser Mobile app much, but it does give you the option to use a mostly darker screen for nighttime web browsing (darker than usual, e.g., with Safari). The top portion of the screen, which has the controls, remains at the normal brightness level. I imagine the developers did that so you could never inadvertently dim your controls down to where you couldn't find them.

However, that section of normal brightness detracts from a full-screen "dark-browsing" experience. Perhaps the developers could instead have restricted the lower limit of darkness, such that the controls in many instances would remain visible?

I imagine the developers wanted to save space at the top of the screen for their controls, so they removed the common iOS top bar which shows the clock time in the middle. Normally you can tap that time display to zip to the top of the document, but I don't see any way to do that in Late Browser Mobile.

This is the only app I can think of which displays an ad (the same one) twice, once at the top and once at the bottom of the initial search screen. Thankfully it seems only one would be visible at any one time, depending on how you've swiped the screen up or down, and no ads show when you've left the initial search screen.

The very bottom of the initial search screen has a 5-digit "LED" display which shows a number, which seems to be strictly ascending in my usage, and may indicate some quantity of the data you have downloaded in your browsing.

8/24/11: Wow, I didn't realize how many free browsers there are in the App Store. While I don't think any are likely to dethrone my favored Opera Mini browser, perhaps I'll find other browsers with a night mode.

Opera Mini 6 web browser vs iOS 4 Safari

12/17/11: This entry is about Opera Mini 6/6.0.1 vs iOS 4 Safari, and is now largely static. See my subsequent blog entry on Opera Mini 6.5.1 vs IOS 5 Safari for a newer evaluation of the two browsers.

This entry gets updates, either unadvertised or advertised-with-dates, over time. I mostly read text while browsing the web on my iPod, which is probably one reason why Opera Mini works so well for me. I have little to say about images and videos in Opera Mini.
10/29/11: Most of the following discussion of Safari's capabilities refer to iOS 4; iOS 5 Safari has different, improved functionality.

I nursed my wounds on my iPod for some time from having upgraded from the excellent version 6 to the more-crash-prone-and-generally-worse-but-usually-still-better-than-iOS-4-Safari version 6.0.1, and was not in a hurry to upgrade further (on the iPod) -- once bitten, twice shy.  I did eventually upgrade to 6.5.1, which I consider is better than 6, though not by a huge margin.

7/15/11: Version 6.0.1 was released in 7/2011. I believe they changed the formerly obligatory single column display into the Single Column View option in Settings. That was likely done to allow the universal binary to display non-mobile websites normally on iPads, which have much larger screens. In any case, I happily use Single Column View on the iPod. However, Single Column View is not the default, which means if Opera ever crashes (7/27/11: ugh, a far more frequent occurrence with 6.0.1, but how much of that is related to 6.0.1 versus Opera server issues is unclear) or is fully closed, as I described here (e.g., to release any RAM it's holding onto), it is necessary to select Single Column View again. I normally keep Opera in RAM all the time.
(7/21/11: If you like 6.0's single column display on the iPod, you would likely be better off not upgrading to 6.0.1.  I have to re-select 6.0.1 Single Column View at least as often as each time Opera Mini crashes, which, sadly, is frequently.)
Upgrading to 6.0.1 displaced one of my existing 9 Speed Dial entries with an Opera page, but I eventually reset that.

The free Opera Mini web browser is an alternative to Apple's Safari browser, with various pluses and minuses. Opera Mini version 6 was released in 5/2011. Wikipedia has a decent article on it: http://en.wikipedia.org/wiki/Opera_mini, which also links to the interesting http://dev.opera.com/articles/view/opera-mini-web-content-authoring-guidelines/. A list of technical specifications can be found at: www.opera.com/mobile/specs/. Here is a CNET review.

I use both Safari and Opera Mini regularly, but actively try to make greater use of Opera Mini, which I feel has more advantages for the iPod. An iPod is typically connected to the Internet less often than an iPhone, so some of the following items (e.g., Saved Pages) are more significant for iPod users like myself.

PROS:

• Opera Mini does not automatically reload a page when you tap the back arrow to return to it, at least if you return within some period of time (ever?). Thus, if you are reading a page which has multiple links to other pages, e.g., Google News, then tap to read an article, returning to the original page will not invoke (frequently pointless and time-wasting) reloading, unlike in Safari. Also, if you load pages into different tabs while you have Internet access, but later lose that access, you can still read those pages, even without having stored them as Saved Pages. RAM issues mentioned below will still be applicable.
• Unlike in Safari, you don't have to switch away from the current tab to open new pages, because you can open links in background tabs (tap-hold, then tap on "Open in New Tab"). This is helpful while, e.g., reading through all headlines in Google News, allowing you to open all stories you'd like to read in background tabs. RAM issues mentioned below will still be applicable.
• Unlike Safari, Opera Mini allows saving of static copies of web pages on the iPod, letting you read or reread them later even without wireless Internet access. That can be useful to save pages for recipes, technical reference, humorous articles, or for any other reason, e.g., because you don't have time to read them right away. Although I was once annoyed that I had to make 7 separate Saved Pages for an article (and I've seen articles requiring even more pages), that effort did serve me well since I was imminently losing Internet access, and I was able to read the (interesting) article soon afterward, while waiting in a store.
• At least 15 (someone else can test for the maximum number...) tabs are possible, exceeding Safari's limit of 8. RAM constrains the total number of tabs effectively usable; "The page has been cleared to save memory." message is what you are left with content-wise on a tab when you run low on RAM.
  9/8/11: Bummer, my Opera Mini had a serious problem and lost my saved pages. Rather shocking to discover I no longer had any entries in Saved Pages. However, that did make me realize that I was saving a large number of pages (in these 2 months of using 6.0.1), but only in a relatively small number of instances loading any of them again, so I wasn't too upset. From this Opera Mini forum thread, it looks like saved pages may be lost again upon an eventual upgrade of the iOS Opera Mini
• If you make an account on Opera's servers, you can use Opera Link to determine at what frequency to save both your nine Speed Dial targets and the state of your bookmarks there, for future restore (e.g., in case of a serious crash) or for sharing on another device(s), including on a pc.  Automatic syncing is possible, but I prefer to sync bookmarks manually, which avoids attempts at same when you know (or perhaps, even when you don't know) that you lack wireless Internet access.  Opera Link can also be used at any time on any Opera Mini instance device, so it is not linked inextricably to an Apple ID like iOS 5 Safari's Reading List. Although I didn't test this, it appears that if you use desktop Opera, there is supposed to be an Opera Mini folder for bookmarks, which is the extent of the bookmarks that get synced with Opera Link.

CONS:

• Opera Mini does not provide end-to-end encryption. If you don't trust their company, don't use it for anything requiring credentials or anything to which you're concerned about them having potential access.
• There is a short startup delay as it makes the connection to the Opera proxy servers ("calls home").
• Presumably because of the Opera proxy server, has extreme difficulties using maps.google.com effectively; I strongly advise using Safari for that. Even Safari cannot yield copyable text, though.
• On rare occasions, my initial attempt to bring up a page doesn't succeed, which I imagine is an Opera proxy server issue.
• Opera's proxy servers may lead to this side effect:
  Going to, e.g.:
  http://www.cnn.com/2011/HEALTH/05/26/dumb.doctors.office.ep/
  prompts you with:
  It looks like you are from outside the U.S. Would you like to make International your default edition? Yes | No Close
  which I chose to simply ignore.
• Only Safari can Add to Home Screen, using apple-touch-icon.png  when available (not favicon.ico, as it turns out; according to http://www.webmasterworld.com/html/3560399.htm). I had to remove some such Home Screen icons to prevent inertia from making me mindlessly use Safari. Opera Mini's Speed Dial is a partial substitute.
• The upgrade from 5 to 6 messed up images in previously saved pages from The Onion (and maybe from other websites, I didn't check). Not a big deal, I re-saved some pages to restore the images. However, images are rarely, if ever, crucial for me.  (7/22/11: No obvious similar problems from the 6.0 to 6.0.1 upgrade.)

OTHER OBSERVATIONS:

• Using Single Column View ensures that, because of its size, text will be pleasantly readable in portrait mode, at least for me. http://www.thechessmind.net/ is a chess blog which I have often been reading of late. In Safari, I sometimes feel the need to switch to landscape mode to make the text more legible, but the text has always been fine to read in portrait mode in Opera Mini.
• When using Single Column View, some items which might typically (as viewed, e.g., while not using Single Column View, or in Safari) be unobstrusive on the side of a web page may appear, sometimes as a large clump, at the top or bottom. I have gotten used to that, and simply swipe to get past the clump, if it's at the top, to get to the real content, e.g., on http://www.thechessmind.net/.
• Find in Page: The Done button means done with searching; search happens as you type. Can search repeatedly in a page. Safari can find in page also, although it's probably somewhat less intuitive; see, e.g.: http://www.tipb.com/2010/09/16/ios-42-features-find-text-safari-web-page/
• Only 1 Speed Dial Start Page is possible per tab. So if you start there, then keep going "forward" to additional pages, you'd have to tap the back arrow, potentially many times, to get back to the Speed Dial Start Page again in that tab. I tend to keep common destinations in both the Speed Dial Start Page and in Bookmarks, so in some cases (precisely 9 - the number of possible Speed Dial target pages), I do have the Bookmarks route as an option, but it's more to the point to just open a new tab, which starts on the Speed Dial Start Page.
• In very early June 2011, it seemed that it was sometimes necessary to scroll to the bottom of a page to be able to activate the Opera controls (some Opera proxy server problem?), but this problem seemed to have been fixed by 6/5/11.
• In very early June 2011, the links returned for a Google search for "tornado hurricane difference" could not be opened with taps (some Opera proxy server problem?). I did the same search in Safari to get to those links, then copied the most interesting link to Opera Mini in order to save its content. This "tappability" problem seemed to have been fixed by 6/5/11.
• One day in mid-June 2011, I was unable to reach websites ("Unable to connect. Please review your network settings."). I have many of the same sites bookmarked in both Opera Mini and Safari, so I just switched to using Safari for a time, switching back to a once-again-working Opera Mini later in the day. As long as Opera Mini problems aren't an "overly common" occurrence, I am unlikely to switch to any other browser as my main browser -- the Pros of using Opera Mini are that useful to me.
• To copy lengthy text from a web page (I only tested using Single Column View, my normal mode of operation), it is more effective to select text starting from the bottom and press-dragging up to the top. Selecting text from top to bottom seems fraught with pitfalls which can prematurely stop your selecting, when you'd have to start all over again by going to the top of the web page (press the time at the top center of the iPod screen to do that), then again pressing and holding on non-link text until the Select Text option appears, tapping that, then press-dragging again to select. A reasonably rigorous test page for this, about hiking Mount Washington. Although you could save the entire web page, copying its text elsewhere can be useful in some situations.
• 9/4/11: Power-User settings are available by going to config: in the location bar, as described further on http://www.guruslodge.com/bmobile-phones-tutorial-and-solution-centerb/operamini-secret-codes/, which I just discovered. Changes apparently survive Opera Mini crashes, unlike the Single Column View setting. For my own usage, I turned off the Phonenumber detection, which I suspect is probably only of use if (a) you have an iPhone (which I don't), and want to call such a number immediately, or (b) you normally use iOS assistance to add new contacts (which I don't, for reasons mentioned here).
