Hacker and unc0ver lead developer Pwn20wnd dropped the first unc0ver v2.2.0 pre-release for public testing on Sunday with an extensive list of changes, but it now seems that was only the beginning.

On Monday, Pwn20wnd pushed at least two new revisions to the unc0ver v2.2.0 pre-release, dubbed b3 and b4. The changelog appearing on Pwn20wnd’s official GitHub page cites the following changes in these revisions:

01/21/2019 – v2.2.0~b3 was released for public testing with the following changes:

– Fix theoretical bugs

– Improve assertion

01/21/2019 – v2.2.0~b4 was released for public testing with the following changes:

– Experimental performance improvements

Evident from the nomenclature at work here, these builds aren’t official public releases for the masses, but instead beta releases intended for public testing. That said, these builds are only recommended for experienced jailbreakers who possess basic troubleshooting knowledge in case of potential bugs or instabilities.

If you aren’t comfortable using a pre-release version of unc0ver, then we advise you to use the latest official public release (v2.1.3) instead; it too can be downloaded from Pwn20wnd’s official GitHub repository.

Unc0ver is a semi-tethered jailbreak just like Electra, which means you must re-run the tool after every reboot. That aside, it bundles a newer iOS 11-optimized build of Cydia that sports the official seal of approval from Saurik himself.

If you’ve never used unc0ver before, and plan to do so now, then you can follow our in-depth tutorial about how to install and run the unc0ver jailbreak. The unc0ver jailbreak tool supports all devices that can run iOS 11.0-11.4 beta 3. If you run into any problems while using unc0ver, then you can report bugs here.
