I have 1.1.3 update. My screen is frozen - help! It's all black except for a small circle in the middle, and the top bar shows reception, the time, and battery. The time and battery are stuck at when this first happened - 5:14 PM and it's over 5 hours later. Holding the menu button down does not help. Holding the power button down does not help. Not sure what else I can try. Will the battery eventually run out and then I can restart? When I dock it to my computer, it's attempting to sync in iTunes, but it just cranks like it's trying but really does nothing. HELP!
