Hi, I have jailbroken iPhone 3G ios 4.1 (8B117) with model firmware 05.14.02. Is there anyway I can restore it to factory settings with itunes? I would like to upgrade it to ios 4.2. I have factory unlocked my iPhone but I need to restore with itunes to make it work. Please give me suggestions. I have searched all over internet but didn't find right solution. If I restore my iPhone with itunes it gets stuck in recovery mode.
