In a series of Tweets shared previously, Pwn20wnd said this update would resolve every known problem with system apps and services and that it would improvebatterylife substantially by addressing daemon issues that affected some users upon jailbreaking. That said, this is an update you won’t want to skip.
In case you missed it, unc0vernow supports all iOS 13.0-13.3 devices. Originally, supporting onlyA12(X)-A13 devices on iOS 13.0-13.3with the help of Brandon Azad’soob_timestampexploit, a revised exploit dubbedtime_wasteby Jake Jamesintroduced support for A9-A11 devicesthat were already jailbreakable withcheckra1n. This makes it possible to switch between checkra1n and unc0ver on supported firmware versions when needed, such as when a computer is out of reach.
