iPhone 6 isn't simply bigger it's better in every way. Larger, yet dramatically thinner. More powerful, but remarkably power efficient. With a smooth metal surface that seamlessly meets the new Retina HD display. It?s one continuous form where hardware and software function in perfect unison, creating a new generation of iPhone that?s better by any measure. The biggest iOS - iOS 8 is the world?s most advanced mobile operating system. And with incredible new capabilities and features designed to make the most of a larger display, iOS 8 doesn?t just work seamlessly with iPhone 6. It makes every experience feel bigger and better. By creating iPhone 6 and iOS 8 together, we optimized the software to enhance the physical design. iOS swipe gestures were designed to be more fluid across the seamless form, making it easy to navigate iPhone with one hand.
