As promised, hacker Pwn20wnd released the fortieth beta version of the unc0ver jailbreak tool v3.0.0 with full support
The new beta version contains Cydia and an updated version of Cydia Substrate for all supported devices.
Devices with an A12 (X) processor, like the iPhone XR, XS, XS Max and iPad Pro (2018), are not yet supported, but this will soon change.
It is worth noting that the version of unc0ver v3.0.0 is still at the beta testing stage, and we recommend waiting for the release of the public version without bugs.
If you have already installed the previous unc0ver v3.0.0 beta, be sure to download the update to enjoy the new features and improvements.
The latest public version of the unc0ver tool is v2.2.6, it supports iOS 11.0-11.4 beta 4. Both the public and beta versions of the tool can be downloaded from the official Pwn20wnd repository on GitHub.
Recall that you still have the opportunity to roll back to iOS 12.1.1 beta 3 in order to be able to install a jailbreak.
