Microsoft may be readying a major update to Windows Phone 7 that would help it catch up to its rivals, most of all in web browsing, Microsoft sources claimed on Wednesday. So far codenamed "Mango," the update would add HTML5 to the web browser and would add support for Silverlight outside of WP7's own foundations, possibly as a plugin. It would be much larger than the one or two minor updates expected in early 2011 and could be tantamount to a "Windows Phone 7.5," ZDNet understood.
