What can I do with this iPod I bought from A thrift store and it is locked. ?

Congrats. You bought a stolen iPod.

Recycle it. 
     
Did you Not know it was locked Before you bought it? 

It is probably stolen goods. Return it for a refund.

You can stop LYING. A thrift store would have confirmed it WAS NOT locked before selling it. A quick call to Apple would have confirmed that.

Factory reset and use it. You could also hack into it and copy all the songs, then factory reset.

Well you lost 100 dolors 

It may not be stolen. A person might have donated it without erasing the contents. But none-the-less, it's locked, and if you can't prove lawful ownership, you might as well recycle it for credit with Apple. The ipod is registered and unless you are the registrant, not a thing you can do with it.

Take it to the cops and tell em "I got this from a terrorist". Theyll unlock it for you
