What does “jailbroken/rooted device” mean?
Jailbreaking refers to the process of removing all restrictions imposed on an iOS device. iOS devices that are vulnerable to being jailbroken include but are not limited to; Apple iPad, Apple iPod Touch, Apple TV 2 and all Apple iPhone smartphones.
Rooting is the process of allowing users of smartphones, tablets and other devices running the Android mobile operating system to attain privileged control (known as root access) over various Android subsystems.
Jailbreaking and rooting allow root access to system files that can be manipulated to enable installation of apps, themes, and extensions that are not supported by Apple and Android, or unavailable for download on Apple App Store and Google Play Store.
