To those who are confused AT&T changed upgrade rule. There are NO 12 month full upgrades. You sign a 24 month contract you're eligible for full upgrade in 20 months. After 6 months into new contract you are eligible for partial iPhone upgrade @ $250 + cost of iPhone for 2 year contract. If you have 12 month full upgrade now you are grandfathered. This is why those that bought 4S 10/2011 are showing full upgrade eligible 5/13 which is 19/20 months. Those who bought 4S will be able to partially upgrade when iPhone 5 comes out in 12 months @ $250 + subsidized iPhone price which will be $450 for 2 years. This is it and confirmed from CS at AT&T store.
