T-Mobile announced today some interesting updates to Bobsled. In collaboration with Vivox, Bobsled is T-Mobile's bid at providing "a universal way to communicate however and whenever when connected to the Web."

First in the lineup of T-Mobile's improvements to its Bobsled service is the ability to call, message, and voice message their Facebook contacts at any time. To implement this service, T-Mobile offers the ability to turn on a sort of Bobsled toolbar (in the form of a Facebook app) - a tab that displays in your browser (meaning you see it almost all the time) and slides along web pages, allowing for quick access to calling options.
