I bought an unlocked Iphone recently. It's somewhat beat up, nothing bad. I decided to format it, to erase all the previous user's crap lying around in it. Only problem- it won't start now, and when I try to restore it in iTunes, it won't read the phone as being connected to the computer. When I attempt to turn it on, I get a picture of an apple, with a loading circle that'll freeze every few minutes; then the phone resets itself. Help please!
