Speaking at Nokia World in London today, Windows Phone top dog, Joe Belfiore, confirmed that Facebook will get a Mango makeover next week.  Aside from fast-switching, the improved Facebook app will include deep linking capability, the ability to link features like Messages and News Feeds to the Start page. 

Belfiore would not elaborate too much on what other features would be in the update, but he did say that it will work in conjunction with the current Facebook integration that is already built into Windows Phone. The free update is expected to be released on Halloween.
