Microsoft's update to add copy and paste text to Windows Phone 7 may just be a prelude to much larger updates that put it more on par with Apple and Google, tips divulged this morning. The company would catch up in text editing with an update in January that might go live at CES, but an update at the Mobile World Congress show in February would dramatically expand the available support. It would open up programming interfaces for some multitasking, add in-app downloads and allow more user customization, WinRumors was told.
