It is becoming increasingly difficult to break the security of iOS, Apple’s mobile device operating system. With each new update holes and bugs are plugged that could be used to jailbreak, the method that allows installing modifications not approved by Cupertino’s.
This, added to the fact that interest in caching with the iPhone and iPad is at a low level, means that developers are not encouraged to investigate either. However, iOS 12 is susceptible to jailbreak and there are tools for any user to do so, such as unc0ver.
The creation of the @pwn20wnd team has had around 50 beta versions until the final unc0ver 3.0.0 was released.
@pwn20wnd assures us that with the final version of unc0ver 3.0.0 we will hardly encounter any errors that could cause unexpected failures on the iPhone and iPad with operating system iOS 12 – 12.1.2.
But as in the trial versions, unc0ver 3.0.0 is not compatible with all iOS devices available on the market. Only those using processors prior to the A12 Bionic will be able to perform jailbreak, i.e. generations prior to the 3rd generation iPhone XS, XS and iPad Pro.
As indicated by iPhone Hacks, support for these devices will arrive in the future, but only when Cydia Substrate or Substitute is updated to support the latest Apple smartphones and tablets.
How to upgrade to the latest version of unc0ver
If you already have jailbreak on your iPhone or iPad with unc0ver and you want to update it to the latest version the procedure is quite simple. You just need to download the latest IPA file and install it on your device using Impactor or Reprovision and then perform the jailbreak again.
If you are in a later version of iOS, you will not be able to go back to an older version to perform jailbreak since Apple stops signing old releases.
