i have an iphone 3gs running ipad baseband jailbroken with pwnage tool on itunes 10, and itunes suddenly stopped recognizing the phone when its attached via usb to macbook. i haven't had any problems lately, and havent done anything to cause this. I have tried different usb chords, restarted itunes, restarted the computer, restarted the phone, and rejailbroke the phone. itunes just wont recognize it. is there anything i can do without restoring my iphone?
