I go with T-mobile instead? I currently have a Sony Ericsson flip phone, and want to upgrade to a Blackberry Bold 9700. My 2 year contract has expired with AT&T, so I can get the Bold for around $199 with a 2 year contract instead of $499 on it's own. Now here's the problem... When I'm inside my house, I get around 1 to 3 bars on my Sony Ericsson phone which fluxuates up and down constantly. I'm thinking if I got the Blackberry with AT&T again, I'd get the same reception and would probably get dropped from the internet. I have no idea how T-Mobile's coverage would be inside my home. What should I do?
