Well, it's a day late, but Tango, the video-chat app for Windows Phone, is finally here. So for all of those folks with a Samsung Focus S, Flash, HTC Radar or Titan, you'll want to pick this little guy up and give it a go. From the app description:

Tango allows you to make free phone calls and free video calls over 3G, 4G, and Wi-Fi. Make calls to any other person who has Tango installed on their smartphone, tablet or PC. Start a Tango call with just voice, and easily move into a video call when you have something to share. It’s easy to use, it’s fun, and it works.

Tango Features:

  • Free calls between Windows Phone, Android and iOS phones and tablets, and PCs
  • Save money with free international calls to other Tango members
  • Start a phone call with Tango and switch to a video call when you have something to show by tapping the camera icon
  • We automatically find the friends that already have Tango
  • No log in and password - create an account in less than five seconds
  • Invite your friends by Text and Email
  • Simple and easy to use
