iPhone OS 2.0, the second major release of iOS, became available on July 11, 2008 with the release of the iPhone 3G. Devices running 1.x are upgradable to this version. This version of iOS introduces the App Store, making third-party applications available to the iPhone and iPod Touch. Prior to the public release of iPhone OS 2.0, Apple held a keynote event to announce the iPhone OS Software Development Kit ("SDK") to developers.
The most noticed feature of iPhone OS 2 was the App Store. Before this feature was introduced, the only way to install custom applications on the device was via jailbreaking, which is strongly discouraged and unsupported by Apple. There were 500 applications available for download at the launch of the App Store, though this amount has grown dramatically since then. Now, App Store has more than 1.5 million apps as of 2016.
iPod Touch price
iPhone OS 2 cost $9.95 for iPod touch users and free for iPhone users.
