The pre-release versions of unc0ver 3.0 keep coming. The latest release offered by the Pwn20wnd-led team features functionality aimed at those running iOS 12 on their devices and gives root remount access to the underlying filesystem.
It’s very evident from the uncover 3.0 release schedule that this particular version of the unc0ver jailbreak is not only going to be released into the public domain with a heap of worthwhile improvements but that it’s also going through extensive testing to ensure that when it is actually released that it’s stable and functional. That is evidenced by the fact that we are currently seeing beta number 26 in the hands of testers.
Beta 23 of unc0ver was released with support for RootFS Restore on iOS 12, which was then followed up closely with the release of beta 24 which included reworking the detection of whether or not the device is jailbroken, amongst other small changes and improvements, including enabling the aforementioned jailbreak detection on iOS 12 devices which are attempting to use the unc0ver jailbreak IPA.
Subsequently, betas 25 and 26 were also pushed out following on from those releases, packaged together with some clean-up work to add additional debugging support and to ensure that some of the logic for “log window pipes” was properly cleaned up within the codebase.
Interestingly, even though unc0ver is having a lot of time and work invested in it, it is important to note that it no longer includes Substrate or Cydia as part of its payload due to ongoing compatibility issues. It’s also worth wondering just how long unc0ver has left in terms of it being the defacto jailbreak on offer considering that we’ve already seen some movement as far as iOS 12 is concerned with offerings like rootlessJB.
That product is currently being offered aimed at developers only as an SSH-based dev-only jailbreak but it’s likely that progress will be made to make it public in due course.
Until then, it’s great to see additional progress in place to ensure that unc0ver is as feature-packed and as stable and reliable as it possibly can be whilst it is still being offered as a public solution.
