In a treat for the iOS jailbreak community, Pwn20wnd (https://github.com/pwn20wndstuff) has released unc0ver v3.3.0 betas 1 and 2 to the general public with official support for all firmware versions up to iOS 12.2 . The exploit, named "Sock Puppet", is intended to work on all A7-A11 devices but excludes A12(X) devices. In a follow-up Tweet, Pwn20wnd added that the exploit appears to be broken on 4K devices (namely the A7 and A8 varieties) at the time of this writing, but he is looking into fixing this and notes that the Sock Puppet exploit brings with it some reliability issues.
