so I recently got a tmob pearl unlocked for at&t. everything has been working fine since i got it a week ago, but when i drove up to the seattle mariners game yesterday from portland the service changed from gsm to edge. and now it says data connection refused at the top. can anybody tell me what this means?? thanks a lot.

Mine does that once in a while. Pull the battery for a few secs, put it back in. That should fix it. It's only happened once tho. Kinda annoying.

Many times just turning off the wireless radio and turning it back on will fix this. (quicker than the battery pull, if it works.)
