Iphone 4


When creating iPhone 4, Apple designers and engineers didn’t start with a clean sheet of paper. They started with three years of experience designing and building the phones that redefined what a phone can do. iPhone 4 is the result of everything they’ve learned so far. And it’s all contained in a beautiful enclosure a mere 9.3 millimeters thin, making iPhone 4 the world’s thinnest smartphone.

While everyone else was busy trying to keep up with iPhone, we were busy creating amazing new features that make iPhone more powerful, easier to use, and more indispensable than ever. The result is iPhone 4. The biggest thing to happen to iPhone since iPhone.
