Apple’s iPhone has done quite a bit to change the mobile market. It has ushered in the touch-screen craze, delivered an easy way to get third-party programs onto the platform, and generally changed how all other mobile phones are judged. But one of the most significant changes the iPhone initiated was the growth of gaming on smartphones. Thanks to the Apple App Store, more and more people are downloading games like Angry Birds, Cut the Rope, and countless others. The iPhone is now a full-fledged gaming device that, by all measures, can be compared to the Nintendo DS and Sony’s PSP.
