I tried to reboot my iPad 2 and after I slid the power off slider, the little revolving circle just keeps circling. After about 10 minutes I connected it to my PC and I got an error "iTunes could not connect to this iPhone due to an unknown error (0xE8000065)." I've tried holding the Home and power buttons in different combinations, but nothing works. Anyone have any ideas? I guess a trip to the Apple Store is on the agenda for tomorrow. It's now been 20 minutes and the little circle keeps turning and turning and turning... Thanks.
