According to AT&T, they refuse to unlock my iPhone 4S (Early Termination Fee completely paid, account closed) due to "ownership being transferred to Tracfone." Their logic is the following: Even though I was a paying customer for years, as soon as you put the magical Straight Talk microsim into your iPhone for 5 seconds it will break the unlock. Therefore, they are not allowed to unlock it. "The ownership shows it is from a reseller." This is despite a full account history they have in front of them (subsidized through AT&T, purchased through them.) Anyone else have this problem?
