iPhone 5s is purposefully imagined. Meticulously considered. Precision crafted. It’s not just a product of what’s technologically possible. But what’s technologically useful. It’s not just what’s next. But what should be next. iPhone 5 set a precedent, with an amazing amount of technology in a remarkably thin, light design. iPhone 5s builds on that achievement with Touch ID – a fingerprint identity sensor. An A7 chip with 64-bit architecture. An even more impressive iSight camera. And ultra-fast 4G LTE wireless. iPhone 5s is the first 64-bit smartphone in the world. And iOS 7 was designed with that in mind, built specifically for 64-bit architecture. Which makes iOS 7 just as advanced as the iPhone it’s on.
