Ice Cream Sandwich adds tons of new features

Also, called Android 4.0, Ice Cream Sandwich is clearly designed to unify the Android experience. And as Matias Duarte, Google's senior director of Android user experience said, it's also built on three design principles: "enchant me, simplify my life, and make me awesome."
