I've read that this is still a problem in 1.42 (seen it buried in the mega-thread and other posts). I'm still on 1.2 and have this problem at least once a week where I answer a call, but the phone keeps ringing and the screen re-locks itself. After unlocking the screen and hitting the phone icon (or selecting it from the notification bar), I get a FC on Phone. Not too excited about wiping/reinstalling just to have this still in 1.42. Was the root cause ever identified and fixed?
