My two lines are the same way. Ordered the iPhone 4 6-15 and can get the No-Commitment price again in 1 year 1 day. Used to be 2 years for me. I thought I read that they were changing that this year for iPhone owners. Switching from the normal 16-18 month renewal cycle to a 1 year cycle. Had something to do with the price of the phones and AT&T wanting to keep their iPhone (Bread & Butter) owners happy, content and keep renewing their contracts.
