While there's a shortage of iPhone 6 Plus's right now, T-mobile 6 Plus's are virtually impossible to come by. Has anyone had any luck buying an out-of-contract Verizon, ATT or Sprint iPhone 6 and then unlocking it? I've heard (but have not verified) that you can buy an out-of-contract phone for any carrier if you insist it is a gift (they may ask for the number of the recipient). Now you have a contractless phone but you still have to unlock it. Well, https://www.swiftunlocks.com offers iPhone 6 unlocking for $100. That seems like it might work, anyone else tried this or have a better idea?
