Couldn't have made it any easier if they did it for you!
Considering the fact that Evasi0n and redsn0w can't unlock the newest firmware on iPhone 5, and I was DETERMINED TO leave AT&T, this was by far the best $26 investment I could have made into my device! MyIMEIunlock.com not only spelled out step by step how to make it happen, they even did all the hard work for me. All I did was enter my IMEI select my carrier and then plug my device into iTunes and voila an unlocked phone that I can now take to a carrier that appreciates their customers! Thanks team you Dunn great!
