Just another small heads up: '4th and Mayor', the excellently designed Foursquare app is now available in the Marketplace. Total cost to you? $0.00, so there's little reason not to grab it, well, unless you don't use Foursquare, we suppose...even then you should still try it.

See our hands-on video from a few days ago for a recap. And get it here in the Marketplace. Hit us up in comments and let us know your thoughts...
