Apple introduced the original iPhone back in 2007, instantly obsoleting every other smartphone on the planet in every way that mattered. Over the next two years, with the iPhone 3G and iPhone 3GS, Apple increased functionality while simultaneously lowering price, taking the smartphone fully out of the niche and making it mainstream. The iPhone 4 and iPhone 4S continued that trend, bringing support for broader carriers and faster speeds, better displays and new, natural language interfaces. iPhone took manufacturing to new levels and the screen to new heights, but most importantly it set the stage for what's coming next - iOS 7 and the iPhone 5s and iPhone 5c, and more. Before we embark on that brave new future, however, we're going to take a look back. This is the story of Apple's phone. Of Steve Jobs' phone. Of the iPhone. And for many of us, our phone.
