go to iTunes on your computer and check what was in the latest update. Edit: nope. it isn't optimized yet.
According to AppShopper, the game was last updated on December 14th, 2009. So I'm guessing no. Actually, that wasn't even an update; just the release of the game.
Thanks. I really want to play it, but want to wait for a Crisp and gorgeous high-resolution graphics as they say =P
