As of now, T-Mobile is the only game in town for getting your Android groove on in the U.S. With that said, the folks in the following areas should be pretty darn happy about 3G expansion and should already be enjoying the benefits of faster data speeds on their G1 Android phones:

Colorado Springs and Pueblo, Colorado; Des Moines, Iowa; and unconfirmed is Salem, Oregon. More expansion has taken place in Denver, Colorado and the Austin and San Antonio, Texas areas as well. This could be the most exciting thing to happen in the Des Moines area this year (I kid, I kid!). Congratulations to those people in the aforementioned markets who now have 3G. Please tell us how it’s going for you!
