Throw all of that logic out of the window. If you’re an iOS 7.x jailbreak holdover, it’s time to stop holding out and just update. iOS 8.1.1 is now in beta, and it has been confirmed to kill Pangu’s iOS 8.x jailbreak. Even if you don’t want to jailbreak right now, it’s still a good idea to go ahead and upgrade to iOS 8.1, so that when the jailbreak does meet your needs, you can still jailbreak on iOS 8.
iOS 8.1.1 is now in Beta version and it doesn’t come with any new improvements or else, it is mainly a bug fix tweak, however, it will not stay in beta very long. Once Apple releases iOS 8.1.1, which could literally be any time now, it could close the iOS 8.1 signing window, and anyone that hasn’t upgraded could be forced to make the direct leap to iOS 8.1.1 if they ever wanted to or needed to.
So we recommend you guys to download and install iOS 8.1 on your device, even if you don’t want to jailbreak. That leaves the possibility open that you can always jailbreak iOS 8.1 in the future if the need arrises, or if you felt comfortable doing so.
Once Apple releases iOS 8.1.1 to the public, you will be forced to download it on your device whenever you wish to update it.
There’s really nothing to help us to calculate when Apple will close the signing window after the iOS 8.1.1 jailbreak is release, but it will probably be fast, perhaps within a few hours of release. That’s because, along with the reasons alluded to above, Apple sees the exploits used in the iOS 8 jailbreak as a risk to its users, and will want to close up these holes ASAP.
With all of this in mind, I fully expect iOS 8.1.1 to release within the next week, and the signing window to be close on the same day. So again. Update now to iOS 8.1 on all of your devices if you have not done so. Otherwise, you will not be able to jailbreak using the Pangu tool at all, and you may not ever be able to jailbreak iOS 8 again. The latter will obviously depend on whether or not additional exploits can be found and if a hacker or a team of hackers like Pangu decide that it’s worth another go.
