T-mobile is rolling out 3G this week like it’s going out of style with Dayton, Ohio becoming the latest recipient of all things 3G. While an unconfirmed launch as of this writing, the volume of emails shows that there is little reason to doubt it’s a city-spread activity. I guess the only real question is… Cincinnati, where are you??

Update: According to T-mobile USA twitter, Rochester, MN also launches today!
