I think you could only unlock AT&T iPhones but you could unlock AT&T iPhone that's when your AT&T contract is up and AT&T will unlock it for you

Tmobile can't and doesn't unlock iphones.
only the original carrier can unlock the iphone 4 or 4s.
sites that say they can are scams.

You need call att to unlock it.
