Development of the iPhone as a product began in 2005 and continued in complete secrecy until its public unveiling. The device broke with prevailing mobile phone designs by eliminating most physical hardware buttons and eschewing a stylus for its finger-friendly touch interface, featuring instead only a few physical buttons and a touch screen. It featured quad-band GSM cellular connectivity with GPRS and EDGE support for data transfer, and it used continuous internet access and onboard processing to support features unrelated to voice communication. Its successor, the iPhone 3G, was announced on June 9, 2008.

The iPhone quickly became Apple's most successful product, with later generations propelling it to become the world's most profitable company. The introduction of the App Store allowed established companies and startup developers to build careers and earn money, via the platform, while providing consumers with new ways to access information and connect with other people. The iPhone largely appealed to the general public, as opposed to the business community BlackBerry and IBM focused on at the time, and, by integrating existing technology and expanding on usability, the iPhone turned the smartphone industry "on its head".
