Bought a used phone locked to a Puerto Rican carrier, who offered no help at all in getting it unlocked. Half of a Benjamin and a few hours later (I had to be patient, but they came through) I got an unlock code and instructions in an email. Bing bang bong my fancy phone is unlocked, and I saved a buck buying a "carrier locked" phone. I had a good time, and I think you will too.

Very fast and easy. The unlocking was done remotely. I wasn't expecting it to be that easy and fast. Great job. Thanks Unlockbase.
