Mackie let me know that Backgammon King Live has been updated by Magmic. The game has been integrated with the new BlackBerry Messenger 6 and its social platform so you can play against BBM friends. You can also chat using BBM during the game. You can still play against online Magmic players or the computer but the BBM gaming is really slick.
It seems like Magmic is offering Backgammon King for free for a limited time only in App World. They did not specify exactly how limited but you better start downloading it if you want it!
