Apple introduced the original iPhone back in 2007, instantly obsoleting every other smartphone on the planet. With the iPhone 3G and iPhone 3GS, Apple lowered prices an mainstreamed mobile. The iPhone 4 and iPhone 4s took the world to Retina and Siri. The iPhone 5 got taller and LTE faster. And the iPhone 5s and iPhone 5c put the future at our fingertips. The iPhone 6 went thinner and faster than ever before, and the iPhone 6 Plus was Apple’s first BIG phone. The latest in the arsenal, the iPhone 6s and iPhone 6s Plus bring new hardware and add 3D Touch — a new pressure sensitive way to interact with your iPhone.
