I tried to erase and restore my jailbroken/unlocked iPhone 2g to factory setting, now all I am left with is the apple logo on the screen. I have let the charge run down and tried recharging without luck and when I hold down the off and home buttons simultaneously the apple logo turns off then comes back on. I have been unable to get anything else from it. Any thoughts?? I have not dropped or in any other way damaged the phone. Is it fried?
