The Zune 3.1 update is available now. It includes some major navigation updates to Zune Social, three free games (Checkers, Sudoku and Space Battle) and "incremental" stability/performance updates to the Zune PC software and Zune firmware. It all sounds like good stuff to us, so go update and succumb to the Sudoku revolution today!
