So, around April of this year, I wipped up a simple UIWebView app to contain the mobile web app of Google Play Music. Background audio worked fine in iOS 5.1.1. I just built the app for my iPod (running iOS 6 beta 2) and now background audio won't work. If someone could take a look at my code, that'd be great. Maybe iOS 6 changes how it handles background audio?
