Microsoft has just unveiled a new feature in Bing that will help Windows Phone 7 users find new apps for their smartphones.  The new feature, a part of Bing Visual Search, shows users in the United States and UK Windows Phone 7 apps sorted by top rated, newest free, newest paid and most downloaded.  You can also view all Windows Phone apps, which number 2383 as of this posting.

To get the full benefits of the new search tool, you’ll need the Zune software installed on your PC (if it isn’t already).

Check out the apps search page on Bing.
