iPhone OS 1 was announced on January 9, 2007, alongside thefirst-generation iPhone, with both releasing on June 29.[3] The operating system lacked an official name upon release, withSteve Jobs being quoted as saying "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 iPhone's touchscreen interface. Other apps included iPod, for playback of music synced from aMac orPC; 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 iPhone OS and 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 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,[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. Less significant changes included support for changing the order of stocks and cities inStocks andWeather, and the ability to disableEDGE andGPRS whileroaming.[15] iPhone OS 1.1.2 was released on November 9, adding additional language support and fixing aTIFF security vulnerability.[16][17]

Other changes 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.[21] iPhone OS 1.1.4 was released on February 26 as the last iPhone OS 1 update for the original iPhone, while iPhone OS 1.1.5 was released on July 15 as the last iPhone OS 1 update for the first-generation iPod Touch.[22]

Asoftware development kit, theiPhone SDK, was released alongside the update and included a set of tools andapplication programming interfaces (APIs) allowing third-party developers to create native applications.[26][27] A number of features for enterprise environments were also introduced, including support forMicrosoft Exchange throughActiveSync for push emails, contacts and calendars; support for theIPsecVPN protocol; and the ability to remotely wipe a device if marked as lost or stolen.[24] Several new features were added toMail, including support for viewingMicrosoft Office andiWork attachments; the ability to delete or move multiple emails at once; support forblind carbon copy; and the ability to select an outgoing email when composing messages. Other new features included ascientific mode inCalculator while in landscape, a search function for Contacts, and Restrictions, aparental controls system that allows users to, via a 4-digit passcode, lock down certain functionality of the operating system, i.e. disabling access to Safari or disabling playback of explicit music.

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. An option in Settings was also added that allows users to turn off the software keyboard'sautocorrection feature.[33] iPhone OS 2.2.1 was released on January 27, 2009, as the final version of iPhone OS 2[34] and contained several fixes, including a fix for SMS messages failing to send.[35][36]

iOS 4 was available as a free update on both iPod Touch and iPhone, marking the first time a major release of iOS was made available to iPod Touch users for free. As a result, the practice of charging users for major software upgrades was eliminated, and all future major releases of the operating system would be made available for all users across iPhone, iPad, and iPod Touch at no charge.[44]
