itunes stopped recognizing JB iphone 3gs

[threetimesdaily]

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?

Try hooking it up to another computer with iTunes to see if it's your phone or the computer.

I had this happen when I restored from a time machine backup, re-installing iTunes fixed the problem.
