Remember these? If you are a digital native there is a chance you never noticed one of them. They were called payphones. No, you could not FaceTime with them, and they did not fit into your pocket. At its peak of popularity, the US had more than 2 million of them spread out on the streets. Look at the design of the iPhone, Steve Jobs has definitely noticed them and put a lot of quarters in those payphones!
