Hello Barry, I successfully unlocked my iPhone 4S from this website iPhone Unlock and iPhone Jailbreak but I've heard that they also unlock iPhone 5's.
Good luck
I unlocked my wife's ( 4S )and my iPhones ( 5 ) at "unlock fusion.com". Cost was $9.99 per phone.. Had a 24 hour turnaround with an email sent to you when phone is unlocked with instructions.
