It appears that T-Mobile's 3G network is about to go from a crawl to a brisk trot, with rumors flying that high-speed service will be added to a couple dozen markets on Oct. 1.

If you're a T-Mo customer in one of the following markets (besides NYC, which already has 3G), you may be in store for a treat this fall.

The other cities which were expected to get 3G coverage by the end of the year are Atlanta, Austin, Birmingham, Chicago, Dallas, Denver, Detroit, Houston, Kansas City, Las Vegas, Los Angeles, Memphis, Miami, Minneapolis, New England, NJ and Long Island, Orlando, Philadelphia, Phoenix, Portland, Sacramento, San Diego, San Francisco, Seattle, Tampa and Washington, D.C.

And if you're in a rural market, hang in there. After all, you've waited this long.
