So what determines if a black or white background is used in an app. i.e. why is message/phone app white but facetime black. Or is it just one of those incomplete things
Same here. This has happened to me on my iPhone 4 at least 5 times since installation. Had to do power+home hard reset to get it back. Always when I've let the phone idle for some time.
With beta 3 now, my iPhone 4 has become completely unresponsive after being in my pocket for about 15 minutes. It's happened three times already since installing it yesterday.
The only thing that would help was a hard reset. But after the hard reset I'm not asked to enter my PIN, which proves, I think, that the phone wasn't even turned off for real. It just didn't respond, no matter what I did. Weird bug.
