Gameloft announced that they will bring 15 of their games to the iPhone platform. Gameloft, as you may already know, has released some iPod games on iTunes already. Pocket Gamer has a mock up of what one of the games may look like.
Interestingly, this screenshot was shown off in Gameloft's keynote speech in the days leading up to the iPhone SDK announcement. Gameloft produces some big-name games for other mobile platforms, including: Tom Clancy's Rainbow Six, Rayman, Might and Magic, and Prince of Persia.
