So i have a 16 gig gen1 iphone. Im running itunes 8 and firmware 2.1. I updated my phone and now i cant get it to work. It was unlocked/jailbroken by ziphone before but after i updated it i had to use pwnagetool to try and make it work but it doesnt. When it gets to the step in the pwnagetool that turns your phone to dfu mode my phone seems to fail at that step. can someone help? ive tried everything it seems.
