Windows Phone 7 update with copy and paste, CDMA support coming in 'early March'

Though he wouldn't give an exact date, Microsoft CEO Steve Ballmer whittled down the availability window for the company's first big update to Windows Phone 7 at his keynote address to the crowds gathered at Mobile World Congress today. The latest message is that it'll be available in "early March," which puts us precious few weeks away — more or less on track with what we'd been anticipating — bringing support for CDMA radios, copy and paste, and performance improvements. Hopefully that clears the way for the 7 Pro on Sprint, eh?
