When I checked a few days ago my eligibility date was something like July 15 or something like that. Upset that I had to pay the $500, I decided to wait. Then AT&T made their announcement. I go to store.apple.com to check my upgrade status and now my date is 5/10/2010...what the **** happened here? Did this happen to anyone else? Should I call AT&T to see what hapened?
