Sprint officially launched its 4G LTE network yesterday, on July 15, in Atlanta, Dallas, Houston, Kansas City and San Antonio. But now, less than 24 hours after launch, Sprint has tripled the number of cities in which LTE is officially available. The list now includes Athens, Calhoun, Carrollton, Newnan, and Rome, all in Georgia; Fort Worth, Granbury-Hood County, Huntsville, and Waco, all in Texas; and St. Joseph, Missouri.

This means that 4G LTE is now available in four different states, with more to come soon.

Sprint has also updated its 4G LTE landing site (available at sprint.com/lte), hinting that Baltimore will be the next major market to get LTE coverage.

Sprint is still claiming that it is on target to have its rollout largely completed by the end of 2013, with more than 250 million people covered with LTE. Time will tell whether or not Sprint will be able to reach this goal, but I have confidence that Sprint will achieve this.
