Plants vs. Zombies for iPhone has received an update for the holidays, featuring festive cheer, minor user improvements and the "I, Zombie" mode. The new mode allows you to take on the role of the invading zombies -- a feature previously implemented in the PC, Mac, XBLA and DS versions of the game.

The update also includes GameCenter leaderboard support for the first time, and adds four new achievements and "Bronze, Silver and Gold Mystery Sprouts." Now, go and clear the zombies so Santa can have a clear LZ!
