Jailbreaking is a process that allows iPhone and iPod Touch users to run unofficial code on their devices bypassing Apple’s official distribution mechanism, the App Store. Once jailbroken, iPhone users are able to download many applications previously unavailable through the App Store via unofficial installers such as Cydia and Icy. These applications can make changes outside of the application, which official applications cannot.

Jailbreaking is distinct from unlocking, which is the process by which a mobile device is made compatible with telephone networks it was not specifically licensed to be used with.
