I just bought an unlocked original 4GB iPhone. The previous owner has it jailbroken and unlocked and is using it with Tmobile. Now that i have the phone, i want to sync it with my iTunes. I can sync the applications and my contacts, but when i try to sync the music, it says that i have to restore it because this iPhone has already been synced with another computer. Is there a way I can get everything synced without restoring the phone? I bought this phone for a friend and I am experimenting with it so I can teach her how to keep it unlocked. Should I restore it and unlock it all over again on her computer? Or is there a way to go around this? Thanks in advanced.
