Well, what do we have here? One of our readers sent us a screenshot from Sprint's Sales Portal that included the above roadmap for its WiMAX rollout this year. A number of the yet-to-be-launched cities we've already heard about -- Chicago, Philadelphia, Dallas, and Charlotte -- but to the best of our knowledge, the rest of them are brand new entries. Additionally, Baltimore residents can look forward to some sort of coverage update in the fourth quarter. We'd be lying if we said we weren't jealous that Salem (population 3,000) and Milledgeville (population 19,000) are getting the wireless network before most of us on staff, but the service has to start somewhere, right? No indication here of 2010 plans, but last we heard that included Boston, Houston, New York, San Francisco and Washington, D.C.

Update: As tipster Carlos points out, Clearwire's website already has some coverage maps for some of the cities listed in the third quarter, as well as some markets not listed here.
