I found an ipod 4th gen but its disabled.how do i unlock it?

Question

I need help unlocking it

Answer 1

An Apple Store w/ Genius bar may be able to help someone unlock
their own Apple iDevice, however since it was found & belongs to
another, about the only reason to unlock it would be to find original
owner and return it. A 'lost-and-found' department may exist at a
local police station or somewhere near where it was found.
Lost items taken to an Apple Store would be handled according to
any policies and procedures they have in place. Whether or not
those unclaimed have any further disposition would be something
to discuss with someone at the Apple Store representing retail
Apple. They may have some process to help return it to an owner.
If you buy an iPod, iPad, or other device and lose the Apple ID one
used to set up the iDevice, an Apple Store could likely be of help if
the person who owns it has proof of purchase in their possession.
This discussion area is mostly comprised of user-to-user interface
with some limited direct contact to hosts and discussion specialists
who occasionally reply to some posts in certain threads. So most
active persons here do NOT represent Apple, or its policies.
Good luck & happy computing!
