What the hell is wrong with my ipod 4thgen nano!?!?!?
please help, every time i plug in my cord for the computer to the ipod the computer recognises it but itunes does not. I have re-installed itunes, bought a new cord and tried that, and im thinking it must be my ipod..
my ipod even has a little thing that slips into the bit where the cord for the computer goes into, made especially for the ipod....!

i am fairly careful with my ipod, i dont let it get wet, and it has a rubber cover on it.

I have also reset my ipod, nothing has happened!??!

please help! muchly appreacitated!
