With Sprint starting up its Windows Phone 7 adventure on March 20th with the HTC Arrive, Verizon is now said to be matching its CDMA competitor with its own offering, the HTC 7 Trophy. We already knew this particular handset would be coming to this particular network in "early 2011," but now WinRumors has narrowed that down to a launch at some point in late March. Verizon's announcement is expected as early as February 28th, this coming Monday, and we're hearing the NoDo update -- the one with copy and paste -- should be preloaded on the device from the start. Should this solid-sounding rumor bear out as foretold, Microsoft should finally be on all US carriers by the start of April.
