The future of T-mobile USA’s 3G network will rely heavily on the success of the HTC Dream / G1 / Google Phone according to many analysts.  In order to recover the costs of expanding the carrier’s network, the $200 Android-powered HTC Dream must sell well.  In order to meet these sales goals, T-mobile has continued to invest in their slowly expanding 3G network, doubling its size and approaching nationwide status.  T-mobile currently operates on the 1700MHz frequency with a very small 3G footprint in place.  With only 9 major cities currently offering 3G service in the US, T-mobile hopes to bring this number up to 27 by the end of the year.

With 9 cities to complete before the October release of the HTC Dream (October 17th release date), the carrier has plenty of work to do.  The current list of cities that have T-mobile’s 3G network up and running are Baltimore, Boston, Dallas, Houston, Las Vegas, Miami, Minneapolis, Philadelphia and New York.  The following cities are expected to go live by the end of September: Atlanta, Chicago, Los Angeles, Orlando, Sacramento, San Francisco and Seattle.
