iPhone OS 1 was announced by Apple at theiPhone announcement keynote on January 9, 2007. It was later released alongside the original iPhone that same year on June 29.[3] No official name for the operating system was given when the iPhone was released, andSteve Jobs was quoted as saying that "iPhone runsOS X", however it was later referred to asiPhone Software.[4][5] During the development phase of iPhone OS 1, there were around 16 or 17 concepts that were developed. Many on the team were skeptical of the feasibility of a touchscreen keyboard, and believed that users would prefer hardware keyboards. A number of different user interfaces were prototyped, including one that involved a multi-touch click-wheel.[6]
iPhone OS 1 laid the groundwork of the iPhone's operating system, including a grid-based Home Screen calledSpringBoard, and a set of 16 built-inapps, including Text, for sendingShort Message Service (SMS) messages, aYouTube app for watching videos hosted on the platform, and Maps, an app built aroundGoogle Maps with support for route directions, traffic conditions in supported regions, and support for finding and contacting businesses. It also featured a version ofSafari, the web browser fromMac OS X, built around the mobile touchscreen interface of the iPhone. Other apps included iPod, for playback of music synced from aMac orPC to an iPhone; Mail, for composing, viewing, and receivingemails; Phone, for taking or making calls, viewing or adding contacts, and listening to voicemails; and Settings, for customizing the behavior of the iPhone as well as its built-in apps, among others. Support formulti-touch gestures, such as pinch-to-zoom, double tap, and scrolling via flicking and dragging was also included.[7] However, the operating system was criticized for not supporting content made withAdobe Flash, lacking support for cut, copy and paste features, as well as its lack of support forBluetooth stereo headphones.[8] It also lacked support for third-party native apps, having support only for web apps,[9] which was criticized by reviewers and developers,[10][11] includingJohn Carmack.[12]
iPhone OS 1.1 was released alongside thefirst-generation iPod Touch on September 5, 2007 as an update exclusive to the device, and added theiTunes Music Store which allowed users to purchase and download music directly onto their iPod Touch.[13] iPhone OS 1.1.1, released on September 27, 2007,[14] brought the iTunes Music Store to the iPhone alongside other changes, including louder audio receiver and loudspeaker volume, support for viewing Mail attachments in both portrait and landscape orientations, the ability to adjust the volume of alerts, additional intervals for passcode locking, and an option inSettings that allows turning on or off double tapping the space bar on the built-insoftware keyboard to automatically insert a period and space. More minor changes included the addition of being able to change the order of stocks and cities in theStocks andWeather apps and the ability to disableEDGE/GPRS when internationally roaming.[15] iPhone OS 1.1.2, released on November 9, 2007,[16] included a fix for a security vulnerability discovered in July 2007 involving theTIFF image format.[17] The update also included bug fixes and support for additional languages.[16]

The update added several new features, particularly in Maps, such as a hybrid map view combining the satellite view and street and place labels, the ability to triangulate the user's current location via the use ofWi-Fi andcellular towers as well as the ability to drop pins to specific locations.[19] As part of the update, the Home Screen received several enhancements, including support for rearranging icons, adding shortcuts to websites from Safari, and up to eight individual Home Screen pages. Other changes included in the update include increasing the amount of SMS messages that can be stored to 75,000 messages from 1,000 messages, and adding support inText for sending a message to multiple recipients.[20] Apps were also changed to run from the usermobile instead of theroot superuser as part of the update.[21] iPhone OS 1.1.4 was the final iPhone OS 1 update for the first-generation iPhone prior to the release of iPhone OS 2, and was released on February 26, 2008, while iPhone OS 1.1.5 was the final iPhone OS 1 update for the first-generation iPod Touch and was released on July 15, 2008 after the release of iPhone OS 2, to users unwilling or unable to update to iPhone OS 2.[22]
iPhone OS 2 was announced by Apple at a keynote held on March 6, 2008, as the first major update to the operating system,[23][24] and was released alongside theiPhone 3G on July 11, 2008.[25] iPhone OS 2 retained compatibility with all iPhone and iPod Touch models that were compatible with iPhone OS 1, and was a paid update for iPod Touch owners, costingUS$9.95, while it was a free update for iPhone owners.[25]

Other changes made in the update include improved performance and stability within Safari, the ability to downloadpodcasts from theiTunes Store over either Wi-Fi or cellular data, improved sound quality ofvisual voicemail messages, and the ability to go back to the first Home Screen from any other Home Screen by pressing the Home button.

With this release, Apple dropped support forthe original iPhone and thefirst generation iPod Touch, which is the first time Apple had dropped support for any device in an iOS release.[44] TheiPhone 3G and thesecond generation iPod Touch were capable of running iOS 4, but couldn't make use of some of the new features like multitasking,[45] and the ability to set a custom home screen wallpaper.[46] This was also the first major release to be free of charge for iPod Touch users.[44] The release of iOS 4.2.1 brought compatibility to theoriginal iPad.[47] The release of iOS 4.3 added support for theiPad 2.[48]
