My laptop had a little problem, so I reinstalled windows, so anyway, I hook up my iPod to my laptop, because the screen says hook up to iTunes, and after I hook it up, iTunes says, "Cannot view (something like that) iPod because theres a pass lock on it, and I did put it on it, and I cant get into my iPod to unlock it, because it says hook up to iTunes. :'(
Disconnect. Shut off iPod. (Hold top and Home buttons and slide...) Hold and KEEP HOLDING the Home button while plugging in to the computer. You will be asked to restore, bypassing the passcode. You will not have any data on the iPod when done - you have to re-sync.
I had the same problem after I installed the newest Itunes. All It means is the Ipod is password protected. Just put in your password to unlock the IPod and it should have worked. At least it did for me.
