What is a jailbreak?

Jailbreaking is the process of removing hardware restrictions on iOS, Apple's operating system, on devices running it through the use of software and hardware exploits; such devices include the iPhone, iPod touch, iPad,etc. Jailbreaking permits root access to the iOS file system and manager, allowing the download of additional applications, extensions, and themes that are unavailable through the official Apple App Store.
