Jailbreaking is the process of stripping a mobile device of certain programmed limitations in order to do things like buy, install and run third-party applications that haven’t been approved or even increase the phone’s processing speed.
Jailbreaking was first used in regard to the Apple iPhone shortly after its release in 2007, Rooting is a term used in reference to the Android operating system to describe a similar process. In both jailbreaking and rooting, you take administrative control over the operating system.
Jailbreaking can open users to serious risk. Here are reasons why you should avoid jailbreaking your mobile devices.

Disabling your device completely.
If you do something wrong during your jailbreak, you may completely “brick” your device, essentially killing the device and rendering it as useful as a paperweight. Bricking has become less common as jailbreaking tools have become more sophisticated, but it’s still a risk. If you do decide to jailbreak, back up your phone entirely before you begin.
The bigger problem is that jailbreaking instantly voids your warranty. If anything ever goes wrong, you’re out of luck. Think twice before you consider jailbreaking or rooting your device.
