# IPhone OS 3

iPhone OS 3 (stylized as iPhone OS 3.0) is the third major release of the iOS mobile operating system developed by Apple Inc., succeeding iPhone OS 2. It was announced on March 17, 2009, and was released on June 17, 2009. It was succeeded by iOS 4 on June 21, 2010, dropping the "iPhone OS" naming convention.
iPhone OS 3 added a system-wide "cut, copy, and paste" feature, allowing users to more easily move content. It also introduced Spotlight, a search indexing feature designed to help users locate specific information on their device, such as contacts, email messages or apps. The home screen was expanded to let users add up to 11 pages, showcasing a total of 180 apps. The Messages app received support for MMS, while the Camera app received support for video recording on the iPhone 3GS, and a new "Voice Memos" app let users record their voice. In-app purchase capability was added to third-party applications as well.
iPhone OS 3 is the last version of iOS that supports the first-generation iPhone and first-generation iPod Touch as its successor, iOS 4, drops support for both models.

### Camera and Photos

## Cost

Upgrading to iPhone OS 3 was free for iPhone. Upgrading to iPhone OS 3 originally cost iPod Touch users $9.95; updating to 3.1.x from 2.x cost only $4.95.
iPhone OS 3 was the last major version of iOS for which there was a charge for iPod Touch users to upgrade. Starting with iOS 4, iOS upgrades became free for all users, including users of the iPod Touch, as the Sarbanes–Oxley Act was revised to allow software upgrades for free with hardware that is not subscription-based.
