Riot Games has announced that League of Legends: Turret Defense is now available for the iPhone and iPod Touch in the iTunes App Store. The game is free and lets players enjoy League of Legends while they're away from their computers.

Here's information on the game straight from the forum post: "In League of Legends: Turret Defense, players strategically select and place upgradeable turrets on the field and defend against waves of minions, dragons and even a couple of the Champions from League of Legends!"

For those of you who don't have an iPhone or iPod Touch, Riot Games plans to launch a flash version in the future.
