Jailbreaking has many benefits: you can customize your iPhone’s settings and home screen, expand your range of app options, remove pre-installed apps, and unlock restrictions set by Apple. But it does so using an app installed on the device without patches. Like untethered jailbreaks, semi-untethered devices will patch the kernel when it reboots. Because untethered jailbreaks require extensive reverse engineering, they are rarely used.Įarly jailbreaks were predominately tethered, but today, semi-untethered jailbreaks are increasingly common. ![]() After the device is exploited, it will automatically patch the kernel everytime it boots up - without the help of a computer or app. While using a tethered jailbreak, you can still restart the Springboard process (the app that manages the iPhone's home screen) without rebooting.Īn untethered jailbreak is performed entirely on the iPhone itself, without having to connect to a computer. Without this software, the device will not power on. Jailbreaking software gives you full access to the root of the operating system and all phone features.Ī tethered jailbreak means the iPhone must be plugged into a computer and booted with special software. There are multiple ways to jailbreak an iPhone, but the jailbreaking exploit is usually executed through a series of kernel patches - or changes to the program at the core of the operating system (OS). On Android devices the process is called rooting. Although it’s possible to jailbreak other phones, the term jailbreaking mainly refers to getting around software restrictions on iPhones. ![]()
