Open Source Objective C Operating System Kernels

unc0ver is an advanced jailbreak tool for iOS 11.0 - 12.2. It's a jailbreak tool that stands out above the rest, as it it just one app that can jailbreak all firmwares. It's also got full-fledged Cydia and Substrate support, and Telesphoreo port for ARM64 devices. It can rejailbreak from the jailbroken state, offers options and utilities for the user, and many more. unc0ver doesn't share private data for diagnostics purposes, and has no inefficient local jailbreak server (jailbreakd daemon). It offers better system security, better performance and more efficient use of battery life. Switching from other jailbreaks to unc0ver is fairly easy and safe. Dedicated migration support ensures that you can make the switch without losing valuable data.
