I live close to the border in a town at&t says they don't support, but the town right next to me they do, even though they have less service. There has to be a mistake on at&t's part because i get 5 bars in the middle of my town, but the town next to me (Which att supports) i get like 2 bars. Well when i signed up for the iphone 4 i did something that allowed me to use the service in my town (I forget). But when i check my upgrade eligibility it says "You don't live in a supported town blahblahblah" How can i get passed this. I just want to check to see when my contract is over
