I just saw that Rene Ritchie, the editor-in-chief of iMore.com just tweeted this comment (it’s a good one):
There are people out there running iOS 6 beta, and complaining that their old apps won’t work. As Mr. Ritchie points out, that is a ludicrous position to hold, as it is a beta (just released) and not a public release.
But iOS 6 is coming, and not all developers will update their apps to iOS 6 by the time it is released this fall (September or October). That will be one of those situations where you might want to invest in multiple apps for a just-in-case scenario. For example, have one quality back-up PDF music reader, just in case. $4.99 for peace-of-mind (and ability to keep using your device) is a sound investment.
