iQuarterback 2 is an excellent little football throwing game from FuzzyCube Software that has you tossing a little pigskin around a football field through multiple game modes. The game recently came out on the iPad, but the iPhone version is brand new. It's just as fun on the small screen, with plenty of targets to go after, and a "Fame" currency that you can use to collect new outfits, accessories, and more. Full Game Center integration lets you check scores and achievements between you and your friends as well.
Plus, the price is right -- the game is a free download, and right now this weekend, the in-app purchase to remove ads is just US 99 cents. The iPad version is a little more expensive, but that's what you get for having a bigger screen, right?
