On July 1, 2011, the Windows Phone Marketplace has reached an important milestone – reaching 25,000 apps in total. While we’ve seen quite a bit of "spam apps" in the marketplace (despite introducing a 20-app limit to bulk app publishing), dozens of quality official apps were added into the marketplace over the past week. Below is a few of these newly added official apps which we think you’ll find useful, check them out:
