What Is unc0ver Jailbreak?

unc0ver is a popular iPhone and iPad jailbreak developed by Pwn20wnd and the unc0ver Team.

It allows users to install the Cydia package manager, add jailbreak repositories and customize supported iOS features.

The jailbreak supports selected Apple devices running iOS 11 through iOS 14.8. Compatibility depends on the iPhone or iPad model and the installed iOS version.

Unlike computer-based jailbreak tools, unc0ver runs its jailbreak process directly from an installed iPhone or iPad application.

You can install the unc0ver IPA using compatible methods such as AltStore or Sideloadly.

After a successful jailbreak, Cydia becomes available for installing compatible tweaks, themes and additional packages.

unc0ver is normally semi-untethered. If your iPhone restarts, you can open the unc0ver app and reactivate the jailbreak.

Some iOS 14 devices also support a special Fugu14 integration, which provides an untethered component for compatible firmware.

unc0ver does not provide jailbreak support for iOS 15, iOS 16, iOS 17, iOS 18, iOS 26 or iOS 27.
