My 3-day old 3G seems to have collapsed: it froze on a webpage, ironically, the AT&T page (!) and didn't respond to input. I tried holding down the home key for awhile and then the power button, but nothing unfroze it. Any suggestions? The battery's dead now and the phone's a brick. Right now I feel like tossing it like a brick and getting a regular phone! Anyone else experienced this?
