bought it off someone else and need my own ID account cant get theres off dont no there password theyve moved
If you go into the settings, does it allow you to add a new account to the device? You should be able to change your account to the master account.
Hope this helps!
Here's another way that might work for you:
Open your iTunes and all the way in the bottom select to sign out. When you sign in, it should ask you for the account, here you select your existing personal account or make a new one.
Good luck :)
I would just restore you iPod, that way it will remove everything else that's there's to.
