Xohm's WiMax Coverage Quietly Live and Working in Six More Cities We saw Sprint/Clearwire/whoever 's Xohm WiMax tested in B-more with speedy results . And now, news from a Xohm employee in Baltimore is that the service is also live and working (albeit in an "unsupported" test capacity) in Chicago, Boston, Dallas, Philadelphia, Washington D.C. and northern Virginia. So anyone with WiMax-enabled hardware in those cities, let us know if you're picking up any sweet 3 mbps pipe out there. [MP3Car ]
