Quick question: I am considering purchasing the iPhone 5 but my contract for my iPhone 4S is not up according to AT&T. I find this hard to believe since I purchased the 4S 64 Gb version on Oct 7, 2011 for $749 -- in other words, no subsidy. Am I right in assuming that I can both unlock my 4S and also am entitled to unlocking a potential iPhone 5 if I purchase it at $849? Totally confused...and hoping for some clarification Thanks!!
