Microsoft watchdog Mary Jo Foley is reporting that Microsoft is prepping a major update to Windows Phone 7 for the fall timeframe. Codenamed Mango, the fall update is rumored to add Silverlight run-time and HTML 5 support as well as additional languages. Foley speculates that Microsoft may ramp up the enterprise functionality with Mango, in particular additional support for Exchange ActiveSync policies that enforce security requirements for mobile devices.

Rumors about the schedule for updates to Windows Phone 7 and what those updates will include have been flying recently. The current best guess is that we are going to see one or two updates in the January/February time frame, quite possible announced or released at CES in January. Many of the talking heads in the industry see that as a likely scenario because the rumored CDMA support would offer carriers like Sprint and Verizon the ability to announce their Windows Phone 7 launch hardware. Microsoft CEO Steve Ballmer is delivering the pre-show keynote on January 5th. One could assume that there would be other minor updates before Mango is released in the fall. Foley also mentioned the possibility of a Windows Phone 8 (codenamed Apollo) launch in late 2012.
