According to the dev of the new exploit Jake James, this exploits now supports all devices on iOS 13.0-13.3. So it seems that people who cannot use checkra1n may now use unc0ver instead.
Or you can use both jailbreak tools checkra1n for the stability, unc0ver for the emergency jailbreak solution when away from a computer.
using this version its also fix some problems and bugs from previous unc0ver jailbreak 4.0 for example.
Jailbreak iOS 13 – iOS 13.3 HUGE Updates! A11 iPhone X and older COMING to UNC0VER! A12-A13 Stability Fixed & NO Computer Jailbreak iOS 13.3. A11 unc0ver Status HERE:
Here iphone 11 pro, the only bug I have is the iMessage pictures. My watch didn’t resync, my app store updates work, Carplay works, everything works fine minus the imessage pictures.
Unc0ver version 4.1.1 brings added stability to the A12 – A13 jailbreak iOS 13.3 tool. In fact, the very exploit used to add stability will also lead to support for those older devices (we have Jake James to thank for that). The semi-untethered unc0ver iOS 13 jailbreaks is coming to iPhone 10 A11 and older because of this! Expect to be able to switch between the unc0ver and checkra1n jailbreaks at will; exciting times.
