Hi everyone. I have a quick question about AT&T's phone unlocking policy. Looking ahead to when the new iPhone 6s / 7 is released next month, if I were to purchase a new iPhone from AT&T and sign a 2-year contract, and then I turned around and decided to terminate my service with AT&T, pay the ETF, and switch to T-Mobile service bringing the iPhone I bought from AT&T, would I be eligible to have AT&T unlock my phone? From what I've read, it looks like an iPhone purchased through AT&T would definitely need to be unlocked prior to switching over to T-Mobile. AT&T's unlocking policy seems to be pretty restricted for subsidized phones if you're still in a 2-year contract, but I'm not sure if they'll unlock a subsidized phone if you break the contract but have paid the ETF. On a side note, did I read correctly that AT&T is the only of the "big four" wireless carriers that's still locking smartphones, or are other carriers still doing it as well? Thanks for any advice!
