When Steve Jobs introduced the original iPhone on the Macworld stage in 2007, he teased it as a revolutionary phone, a widescreen iPod, and a breakthrough internet communicator. Back then, many people were excited about the idea of an Apple phone. In hindsight, the phone app turned out to be one of the least exciting things about the iPhone. Part of that is because we had mobile phones before. From flips to candybars to phone apps on Palm and BlackBerry devices, making phone calls from even a wide-screen, multitouch iPod was nice, beautiful even, but not really revolutionary.
Mobile Safari was, however, an absolute breakthrough.
