I dont have a regional plan, so I would assume that its a full USA plan. I was not referring to the EDGE next to the signal bars, it always said EDGE and i actually had 4/5 bars up in Wyoming (Jackson Hole), and the data was pretty fast (plugged it into laptop and used it as a modem most of the time since the hotel charged way too much for internet). I was referring to the carrier area, I guess, where it usually says T-Mobile but it said Edge, among other things which i don't recall, but I dont know about the roaming. I know that a friend with a treo used it up in Canada with Cingular and got like a $500 bill since it was international data roaming and he had it to get his mail 1x every 5 mins (stupid treo).
