Why even bother rolling something out when its primary purpose is not present? It’s be like releasing a car without wheels, or a console without games (oh wait, Sony did that). But that is exactly what T-Mobile is doing: the first phase of the rollout, however long it may be, will only be using the 3G network for voice. You’re stuck with EDGE for data.
Well, if you’re lucky enough to be getting this “update,” let us know if anything at all changes. Maybe your mom will sound better now — she always sounds so raspy! I’ll call her later and let you know.
