We've been hearing about BlackBerry Mobie Voice System for quite some time now, and with the announcement from WES, we know things are moving along and it will be available later this year. If you're not sure just how exactly MVS works you're not alone. Isaac cleared things up a bit for us, but some things are just better seen then read. The team at BlackBerry has done up a demo video to show off MVS and shows just what goes down. Its a cool 5 minutes that helps to better understand what MVS is all about. Check it out and let us know what you think in the comments.
