Foursquare app for Windows Phone 7? The troublesome program was pulled due to lacking features and a rather sub-par user experience, leaving mayors everywhere unable to verify their credentials for hard-earned discounts. Well fret no more, friends. A new version of the mobile check-in application has been released, showing off a retooled interface that takes full advantage of Microsoft's panoramic UI. Among other features are live tile, tap-and-hold check-in, and a map that shows friends' check-ins alongside nearby specials. Version 2.0, as it's being called, is now available in the Windows Phone Marketplace -- your Twitter followers have probably missed all of your Taco Bell Fourthmeal check-ins anyway.
