After checking with our Red V sources, they whisper to us that the news that WinRumors is reporting is accurate, and Verizon will be adding Windows Phone 7 devices in late March. AT&T was the first to market and offer the first Windows Phone 7 devices in the U.S.

As with Sprint, Verizon will also be adding HTC 7 Trophy to their lineup. The Sprint Windows Phone 7 offerings will arrive starting on March 20th, while Verizon will offer theirs shortly after that. Both offerings are said to feature the “NoDo” update, which adds “cut and paste” support.

While Windows Phone 7 has not lit the world on fire, it has for sure received attention with its very well done “animated tile interface” that makes the smart phone easy to use and a real competitor to other smartphone offerings. It remains to be seen if adding additional carriers will equal more sales; but to start with, Verizon is said to be offering the HTC 7 Trophy for $199 with a two-year contract.
