I only unfortunately only have one iOS device for testing, an iPod Touch 4G which I use as a smart-phone-without-phone, tethered to a Nokia dumb phone or using WiFi. So in other words, I use it for testing but don’t have a completely blank slate that’s normally needed for proper testing.
Some users reported problems with newer versions of AudioExplorer and iOS 5.1, which I was unable to verify, not having upgraded to that version yet myself. I was also under the impression that versions 5.0.1 and 5.1 were similar enough. However, after I was forced to upgrade to 5.1.1 myself in order to use a certain app (DB Tickets), I finally was able to find out the problem: 5.1.1 seems to be stricter about how an app is signed. Plus, my iPod ran builds of AudioExplorer that didn’t run on one of my beta testers’ device. The previous releases 1.3, 1.4, 1.4.1 all had this problem. However, the next release will, with a bit of luck, finally really work with iOS 5.1.
While I’m waiting for the beta testers to test, I took the time to incorporate some of their suggestions, like the ability to manually remove an app from the app listing. This is not only handy if the app is deleted (thus avoiding a complete refresh), but also if you just want to remove an app you’re not interested in (of course, neither the audio files nor the app itself is removed from the iDevice, just the listing in AudioExplorer).
