Apple introduced the iPhone in 2007 and later became one of the world's most valuable listed businesses.
Steve Jobs unveiled the original iPhone on January 9, 2007, at the Macworld Conference & Expo in San Francisco. It combined a mobile phone, an iPod, and an internet communicator in one touchscreen device, presenting a different approach from the keyboard-based smartphones common at the time.
The first iPhone went on sale in the United States on June 29, 2007. Its software initially used web applications rather than a native third-party app store; Apple launched the App Store in 2008, creating a major new part of the company’s platform economy.
The iPhone’s importance to Apple’s market value comes from more than unit sales. It supports services, accessories, developer activity, and customer loyalty. The original device is distinct from later models such as the iPhone 3G, which added support for faster mobile networks and arrived in 2008.
