I have a 1st gen iphone that was upgraded to firmware 2.0. I have made a firmware restore file as specified in the instructions posted on MMI for using Pwnage, but when i try and restore the phone through itunes it keeps failing, error message 06? I am running iTunes 7.7. It does give me the option of choosing my restore file but should i try rolling back to iTunes 7.5. Will this help?
