With the HTC EVO dual-mode 3G/4G handset launching this summer (and nearly ready for pre-order) with built-in hotspot capability, we've got a pretty good idea what all you Americans are wondering: is WiMAX available in my city? Well, buried inside the Clearwire financials is mention of the 19 additional cities scheduled for WiMAXing this summer, joining the 32 markets (pictured above) and 41 million people already served by its 4G network offering 3Mbps to 6Mbps average downloads with an occasional 10Mbps peak.

Clearwire also today announced plans to launch 4G mobile broadband service in 19 additional cities this summer, including previously announced markets Kansas City, KS; St. Louis, MO; Salt Lake City, UT, and the core area of Washington, D.C. Newly announced markets are Nashville, TN; Daytona, Orlando and Tampa, FL; Rochester and Syracuse, NY; Merced, Modesto, Stockton, and Visalia, CA; Wilmington, DE; Grand Rapids, MI; Eugene, OR; and Yakima and Tri-Cities, WA.

Things will get really interesting later in 2010 when Clearwire and Sprint take their 4G mobile broadband network to New York City, Los Angeles, Boston, Denver, Minneapolis, the San Francisco Bay Area, Miami, Cincinnati, Cleveland and Pittsburgh for a 120 million person strong data footprint. LTE who?
