Apple introduced the iPhone at the Macworld conference in January 2007.
Steve Jobs unveiled the original iPhone on January 9, 2007, in San Francisco, presenting it as a combination of a mobile phone, an iPod, and an internet communicator. The device used a multi-touch display rather than a physical keyboard and went on sale in the United States on June 29, 2007.
The first model was developed in partnership with Cingular Wireless, which was later renamed AT&T Mobility. It supported cellular calls, visual voicemail, web browsing, email, and music playback, but it did not initially include the App Store.
The App Store arrived in 2008 with iPhone OS 2.0. People sometimes confuse the unveiling date with the retail launch date: Apple announced the phone in January, while customers could buy it several months later.
