I bought an iphone 3gs 32gb from a guy today. It was jailbroken and I didn't want it to be jailbroken. So, I went to the settings in the phone and selected "reset" then selected "erase content and settings" to do a complete restore on the phone. It's been resetting for 4 hours! The screen will show the apple logo and a spinning gear, then go back to a black screen, then go back to the logo and this goes on forever. Can anyone tell me what to do here?
