i restored it and it didn't have service then either, then i restored it a second time with the pwn restore and it regained service. then jailbroke it and it had service but no contacts, so i restored it a third time after i jailbroke it and had everything.what did you do if you don't mind answering? Its always a nice thing for people to say the solution so others that have the problem can search and actually find answers.
i don't have an answer to that. i don't know how to back it up after jb or even before. i just know when i did a restore it had all my contacts and everything back in the phone.My only concern after reading this thread is that I never did a "backup" before I JB my iPhone. I don't want to lose all my information if something was to happen so can you still do a back up once your phone had been JB? If so how do you do it?
