The XOHM label may be gone, but the potency of Sprint's WiMAX network is still kickin' in and around Baltimore. For those itching for wicked fast mobile broadband outside of The Charm City, Sprint has just unveiled a slew of expansion areas that'll get gifted in 2009 and 2010. As for the rest of this year, folks in Atlanta, Charlotte, Chicago, Dallas, Ft. Worth, Honolulu, Las Vegas, Philadelphia, Portland and Seattle can expect Sprint 4G rollouts, while residents of Boston, Houston, New York, San Francisco and Washington, D.C. can be on the lookout in 2010. In related news, the carrier is also taking this opportunity to reveal that it has "several new 4G devices planned for 2009 and 2010, including a single-mode 4G data card, embedded laptops, a small-office-home-office broadband modem and a tri-mode phone." Lovely.
