You know how to use iPhone from the first time you pick it up. That’s because the revolutionary Multi-Touch interface in iOS was designed for your finger. And the simple, beautiful Home screen is the easiest place to start. From built-in apps to over 500,000 apps available from the App Store. From making a FaceTime call to editing a video with iMovie. Everything you touch is easy, intuitive, and fun.
