I ordered an Unlocked Nokia Lumia 620 through Amazon, and of course it was locked. Having coming across this site, I was a little skeptical at first, but after a few minutes of research and positive feedback from the other customers I knew that this may work. So I ordered my unlock code on a Friday, and although it said it would take 2 business days, I received it the early Saturday morning. I punched in the unlock code and it worked smoothly from there on. I couldn't thank you guys enough!
