Two of TUAW's favorite App Store apps (and probably yours as well) have been updated with new content. Halfbrick's Fruit Ninja has a few new swords to play with, including one that plays piano music as you swipe. There are new leaderboards to fight your friends (and everyone else on) for the Classic and Zen modes. Great free update for a terrific app -- no wonder it's sold six million copies (inspiring Halfbrick to build up an orchard to pay back karma for all that destroyed virtual fruit).
Imangi's great
