Flying out of BWI to Chicago, Boston, Dallas, Philadelphia, Washington D.C. or Northern Virginia? Make sure you pack in that SWC-E100, because we're hearing that Sprint's XOHM WiMAX networks are already live in each of those locales. According to a XOHM representative at a booth in Baltimore, the networks in each of those cities are already up, though they aren't officially supported as they're still "being tested." If any of you XOHM early adopters happen to head to any of the previously mentioned regions, bust out your ExpressCard and see if you get lucky (and then let us know how it goes).
