When the iPhone 4 was released I had 2 of my 3 lines eligible for full or partial upgrades. One a full subsidy, the other a half subsidy and the other nothing. Both upgrades were used on the 4's release but as of yesterday I noticed my line that wasn't eligible till February of 2011 now has a full upgrade. This would have been helpful 2 weeks ago because I wouldn't have used the early upgrade and paid more. Anyone else have their upgrade date move that didn't fall within 2010 grace period set by AT&T?
