Do you mean unlock because your forgot your pass code
or entered it incorrectly too many times? Connect the iPhone
to the computer you usually sync with and use iTunes on that
computer to restore the iPhone.
Do you mean unlock from a wireless provider so you can use
it with another wireless provider? Contact the wireless provider
to which the iPhone is locked and ask that provider if they
offer unlocking and if you qualify.
