Untethered vs. Tethered

What is Jailbreaking?

Jailbreaking is a process that allows iDevice (iPhone, iPod Touch, and iPad) users to gain root accesses to their device, taking down Apple’s harsh resections. Jailbreaking generally installs an app called Cydia that acts as a third party installer allowing users to customize their device with apps, tweeks, themes, and things not possible in the Apple App Store.
