I upgraded to 1.1.2 from 1.02 before I upgraded I installed oktoprep however when I got to 1.1.2 the Jailbreak program said that I didn't install Oktoprep before I upgraded.... I don't know what happened.. I did this on my friends phone and it worked fine but mine got messed up.... I think the iPhone might have been in DFU mode accidently before I upgraded because I was only getting 700MB in iTunes for storage... Now when I tried to downgrade to 1.1.1 to save the phone I get an error in iTunes (The iPhone "" could not be restored. An unknown error occurred (1). Now I'm stuck and have no idea what to do because the jailbreaking software wont work because of the error in that I mentioned earlier. PLEASE HELP ASAP
