T-Mobile has added a new VoIP application called Bobsled that’ll let you make free calls from Facebook Chat and also leave voice messages for your Facebook friends on their walls.
To use the service, you first need to visit www.letsbobsled.com and install the app in Facebook (no need to be a T-Mobile subscriber). Once installed and logged into Facebook Chat, you can “call” your Facebook friends and send voice messages, much like you can make free calls from Google Voice.
T-Mobile plans to extend the service with Android and iPhone apps, video chats, the ability to place calls to mobile and landline numbers, and more, taking on Google and Skype.
If you use Facebook Chat a lot, this could be an interesting and convenient tool, though leaving public voice messages on your friends’ walls is a strange and possibly dangerous idea to me (the messages can be private as well). But then again I’m one of the 12% of the T-Mobile survey who don’t really care for voice chat within the Facebook site. If you’re one of the other 88%, check out the app below.
