I did the update thing and am now in a loop. The gears run for several minutes, then shuts off, the ATT logo screen then appears, sometimes with a black line through the world logo, and then the Nokia screen, then the gears once again. Has been doing this for over 2 hours. If the phone is unplugged, the gears do their thing, the phone shuts off and stays off. I've attempted to do a hard reset, holding the bottom of the volume key rocker and the power switch, but this just causes the phone to go through the described cycles. Not sure what to do next. HELP PLEASE!!!1
