On Friday we published the 42nd episode of Windows Phone Radio. During the show we chatted a bit about the Foursquare app, and how it will take advantage of the upcoming Mango update to Windows Phone. We shot a quick video to show of how you can not only pin the Foursquare app to your start screen, but also specific locations where you check in most. You can find Windows Phone Radio in the Zune Marketplace and iTunes in the podcasts section, or stream direct from here.
