Microsoft plans to refresh the Windows Phone with version 6.5 which will include some big updates to how Windows mobile works. Some things that are planned are gesture navigation and scrolling, ability to preview a voicemail as text when combined with Exchange 2010 and a browsing experience redesigned for touch gesturing.
For those of you familiar with the Zune, you might notice some similarity in navigation on the home screen below.
