My iPhone 3G has been ignored since I got my iPhone 4 last October. I tried entering my passcode yesterday (that I forgot) and after 5 attempts, the screen went white for a second and the apple logo appeared. I did a hard reset a minute later. I then turned on my phone. It shows the Apple logo for a minute then shuts off all the time. Any chance I can try passcodes again or should I just restore the damn thing? Thanks!
