Adding to the already-established voiceover IP options of Google Voice and Skype, T-Mobile announced today it would be partnering with Facebook to enable users to make free VoIP calls through Facebook.
It’s all centered around the Facebook app called Bobsled. After downloading the app, you’ll be able to call friends on your computer with just a click and can even leave voicemail messages (marking them public or private) if you’ve missed them. It’s all free, and you can call pals no matter where in the world they’re located.
