History
Development history
The development of iPhone OS 1.0 and the first generation of iPhone hardware was a combined effort. Only employees from within Apple were allowed to be a part of the iPhone development team. It was a completely secret project, and at the time the team was selected, they weren't even told what they were going to be working on. There were two teams inside Apple that worked on creating the iPhone: one worked on converting the iPod into a phone and the other worked on compressing the Mac OS X operating system to make it work on smaller devices like phones.[1] A team led by Jon Rubinstein worked on developing a lightweight Linux-based version, commonly referred to as Acorn, while another team led by Scott Forstall worked on developing a more compressed and streamlined version of Mac OS X, codenamed purple, to run on the ARM chipset. Tony Fadell, who then led the iPhone team said "It was a competing set of ideas, not teams, and we were all working on it".[2] There were 16 to 17 different concepts. Many people on the team were still hung up on the idea that everyone would want to type on a hardware keyboard, not a glass one. The idea of introducing a fully touchscreen system was very novel to everyone.[1] Many user interfaces were prototyped, including the multi-touch click-wheel. Although many thought it was a waste of time, Apple CEO Steve Jobs insisted on prototyping all concepts/ideas before the Mac OS X-based version of the operating system was selected.
Introduction and release
iPhone OS was introduced at the Macworld Conference & Expo at the Moscone Convention Center in San Francisco, in a keynote address by Steve Jobs on January 9, 2007, along with the original iPhone. At the time, Jobs only said the iPhone "runs OS X,”[3] and according to Chicago Sun-Times columnist Andy Ihnatko, this was confirmed in official briefings and unofficial conversations.[4]
iPhone OS 1.0 was released alongside the original iPhone, on June 29, 2007.[5][6]
The iPhone OS 1.1.3 update cost $19.95 for iPod Touch users.[7]
Apps
iPhone OS 1 did not have any App Store or a Software Development Kit (SDK) for third-party developers to create native applications. Instead, Apple directed developers to create web apps which could be accessed from Safari.[8]

Reception
iPhone OS 1 was hailed as a revolutionary, albeit limited, touch-based interface that redefined mobile computing. Critics praised its multi-touch gestures and the addition of Safari and Visual Voicemail. However, they noted that it lacks cut, copy, and paste, and doesn't support third-party apps.
