There is no master password. You must have the password set for that iPod.
1010 you stupid S.O.B that didnt work ALL I DID WAS COME TO THE COMPUTER LOOKING FOR A WAY TO UNLOCK MY IPOD AND THIS IS WHAT I GET.
you go to ipod menu then settings then into General then Passcode Lock
Use this code as the EAN: 0080878008247
You slide the arrow key to the left, and punch in the code you made.
You can hook it up to the computer and restore all the settings. It will erase all of the apps but you can get past the code.
Unlock it
slide 2 unlock
Go restore your iPod Touch
