Youtube application for our HTC 7 Trophy, Mozart, HD7 or any other Windows Phone 7 device, will allow us to see the videos of our friends from our device. Use this application to play YouTube videos by tapping video links in your email and MMS messages, websites, and apps like Facebook.
Tap the YouTube application icon to open YouTube in the browser, where we can sign in and browse millions of videos, including favorites and playlists.
Also, the application integrates with the Music & Videos hub so we can get to our most-recently played videos and launch YouTube from the hub.
Youtube is available free at the MarketPlace.
