Important Information

unc0ver is designed to be stable and enable freedom from the moment you jailbreak your device. Built-in runtime policy softener allows running code without Apple's notarization and pervasive restrictions. Proper runtime modifications to iOS kernel modify security features as necessary and result in:

No Extra Security Vulnerabilities

unc0ver preserves security layers designed to protect your personal information and your iOS device by adjusting them as necessary instead of removing them. With this security adjusted on your iOS device, you can run your favorite jailbreak apps and tweaks while still being protected from attackers.

Stability & Battery Life

unc0ver is tirelessly developed and rigorously tested with software stability and battery life in mind. If you're experiencing issues with stability or battery life, we recommend searching your device for faulty tweaks.

Reconciliation of Services

Services such as iCloud, iMessage, FaceTime, Apple Pay, Visual Voicemail, Weather, and Stocks, have been reconciled and still work on the device.

Future Software Updates

The ability to apply future updates is retained. Modifications to iOS kernel are done in memory. This results in the jailbroken iPhone, iPad, or iPod touch staying operable when a future Apple-supplied iOS update is installed.

iOS Updates

unc0ver Team strongly cautions against installing any iOS software update that breaks unc0ver as you can't re-jailbreak on versions of iOS that are not supported by unc0ver at that time.

Jailbreak Legality

It is also important to note that iOS jailbreaking is exempt and legal under DMCA. Any installed jailbreak software can be uninstalled by re-jailbreaking with the restore rootfs option to take Apple's service for an iPhone, iPad, or iPod touch that was previously jailbroken.

Thanks to:
pattern-f for the CVE-2021-30883 exploit (Used for iOS 14.6-14.8)
Brandon Azad for the timestamp bug.
Ned Williamson for the socket bug.
