Just yesterday, unc0ver Team lead developer Pwn20wnd updated the unc0ver jailbreak tool to v8.0.0 with official support for A12 & A13-equipped iPhones and iPads running iOS or iPadOS 14.6-14.8. It was trailed by a quick update to v8.0.1 to address issues on A12 handsets running iOS or iPadOS 14.6, but it seems that yet another update was released this Thursday evening in the form of version 8.0.2.
Unc0ver updated to v8.0.2 with exploit reliability enhancements for A12 & A13 devices on iOS 14.6-14.8
