WinRumors.com has learned that Microsoft will begin pushing the Windows Phone 7 March update (also known as NoDo) to carrier-based devices on March 29th. Among the two carriers confirmed so far to participate in this first wave is TELUS Mobility (the other being the UK’s Orange).
A second wave will apparently follow on April 5th with O2 and Vodafone on tap. US deployments may have to wait until AT&T completes its own testing, a process that could take “weeks.”
There is no word yet on when the update could hit other Canadian carriers.
