Hitting stores in new phones on 6 October, and available to download to existing handsets on the same day, the 6.5 update will pack an easier-to-use interface, better browsing capabilities and access to new services including Microsoft My Phone, and Windows Marketplace for Mobile.
The latter is an app store for WinMo applications that comes complete with its own return policy, while the former is a service that will allow you to back up and sync your music, photos, contacts and texts from your phone to the web.
Furthermore, the new Internet Explorer Mobile browser comes with iPhone-crushing Adobe Flash Lite support, and the recently announced Microsoft Office Mobile will allow you to open and edit Word, Excel and Powerpoint documents directly from your phone.
And if you get bored with the look of your phone, you can now choose from different themes and customise your home screen with widgets, with a much improved touch-friendly user interface.
