Basics
Jailbreaking is the process of removing the hardware restrictions on Apple's iOS on devices that are running it through software exploits. Devices compatible include the iPhone, iPod touch, iPad, Apple Watch, and 2nd Generation Apple TV. Jailbreaking allows root access to the iOS file system and manager, allowing the download of unsupported applications, extensions, and themes that are not on the Apple App Store. Jailbreaking is a form of privilege escalation and the term has been used to describe privilege escalation on devices by other companies as well. Restoring a device with iTunes completely removes the jailbreak.
In a nutshell
You get to have themes, free apps, cool features, and look cool.
Reasons to jailbreak
One of the reasons for jailbreaking is to expand the features of your iDevice and bypass the limit set by Apple. Apple often bans apps from the app store, but with jailbreaking there is always a way to get access to the banned apps like Flappy Bird. Also we have awesome emulators like DS, GBA, GBC, GB, N64, SNES, NES, and many more.
