I have 2 friends that are willing to sell me their iphone 5s, one verizon and one sprint. I want to know if i can move one of them over to the Tmobile network (my carrier). I know how to unlock the phones but they have BAD ESNs and I want to know how i can move them over to Tmobile without jailbreaking them. I know how to unlock them using ios6unlock.org, which is free and I have successfully done with my some of my friend's iphones (5) and pennyunlock.com, only a dollar and I have tested it with the iPhone 5 (It works). So community, is there anyway to move them over to Tmobile?
