In blowing up the wireless industry, the iPhone illustrates that big things can come in small packages. The iPhone is a 4.8-ounce of glass and aluminum that has changed the mobile-phone business by taking power away from carriers and giving it to customers, developers, and manufacturers. Fortunately for Jobs and his team charged with creating the iPhone, they had a prototype to show to AT&T at the Macworld convention in the fall of 2006. On June 29, 2007, the iPhone went on sale with big expectations, as the iPhone was supposed to be the quickest-selling smartphone ever and arguably Apples most profitable device. The iPhone has obviously been significant to the fortunes of Apple and AT&T, yet its true impact is on the structure of the $11 billion-per-year U.S. mobile phone industry, where the iPhone has upset the balance of power by showing that the right phone can win customers and bring in revenue. Every manufacturer is now scrambling to create a phone that customers will love, rather than one that carriers will approve. It might seem that carriers nightmares have been realized now that the iPhone has given all power to manufacturers, developers, and consumers, while turning wireless networks into dumb pipes. Yet by fostering more innovation, carriers networks could get more valuable, not less, because consumers will spend more time on devices and therefore on networks, racking up larger bills and generating more revenue for everyone. AT&T is now exploring new services and products, such as mobile banking, that take advantage of the iPhones capabilities. Steve Jobs showed the wireless carriers that the very development they feared for so long may prove to be precisely what they need.
