In addition to announcing free voice navigation for Windows mobiles (read more here), Microsoft has unveiled a free upgrade to Office mobile 2010 for Windows Mobile 6.5 users.

The launch of Office Mobile 2010 coincides with the launch of the fully fledged suite for desktop and has been in public beta version for almost a year.

Office Mobile 2010 includes the ability to edit Word, Powerpoint and Excel files on your Windows mobile.  

Office Mobile 2010 supports gestures for easy navigation, which provide a level of intuition often lacking from complex mobile applications. It also now supports Microsoft SharePoint, which enables you to access document libraries stored elsewhere on your mobile.

Windows Mobile 6.5 users can download Office Mobile 2010 now for free from the Windows Marketplace.
