I just updated to iTunes 7.5 and tried to sync my iPhone "unlocked still running version 1.0.2" and it freezes. I've tried to sync it about 5 times now and it freezes every time. I think maybe Apple built something into the new version of iTunes 7.5 so you have to update your iphone to version 1.1.1 Has anyone else experienced this? Can I update my firmware to 1.1.1 on my iphone? I'm scared cause I bought this iPhone the day it came out and used iPhoneSimFree to unlock it. I don't want to risk bricking my phone. Please any help would be greatly appreciated.
