iOS 12 vs iOS 11 – to upgrade or not to upgrade – that is the question. Read on if you are still on the fence about whether or not to upgrade your jailbroken device.
iOS 11-11.1.2 users
iOS 11-11.1.2 firmware received the most stable jailbreak tool for the firmware. Except for a few bug fixes and patches, iOS 11.2 and above offer no significant advantage to iOS 11-11.1.2 users.
Therefore, you should stick to the original Electra jailbreak, which is has a high success rate and is relatively less buggy than the Release Candidate 1 and above versions.
iOS 11.2-11.3.1 users
iOS 11.2 and above versions offer a bug-free, streamlined experience as compared to iOS 11.1.2 and below.
However, the stability of Electra1131 can prove to be a little spotty at times, especially if you are using the VFS version.
iOS 11.4-11.4.1 users
iOS 11.4, with the exception of iOS 11.4 Beta versions, is yet to receive a jailbreak. And, of course, the same goes for its successor – iOS 11.4.1. For iOS 11.4-11.4.1 users, it’s definitely a toss-up between iOS 11 and 12 firmware at the moment.
Both of these versions look equally appealing. However, iOS 11.4.1 has one big advantage going for it – it’s the lowest firmware version that Apple is still signing.
The first rule of jailbreaking is to stay on the lowest firmware possible and wait for a jailbreak to drop.
Google Project Zero hacker Ian Beer has also promised to release an exploit for this version.
And if you're using the mptcp/vfs exploits for security research (eg with Electra 11.3.1) you should just keep using that. I'll release the 11.4.1 exploits I have but the focus will shift to iOS 12 now 🙂

And it’s for that very reason that I recommend sticking to iOS 11.4.1.
iOS 12 users
iOS 12 is the latest operating system by Apple. Just like its predecessors, it’s months away from getting jailbroken.
Furthermore, this version comes with advanced hardware-based security mechanisms like APRR and PAC, which will make life tougher for security researchers.
The only thing it has going for it right now is sideloading. If you are into sideloading, grab the latest iOS 12-compatible version of Cydia Impactor from here and upgrade.
The final verdict is to sit tight on your current firmware version and refrain from updating to iOS 12.
We still have a one-month window in which iOS 11.4.1 will remain signed. You don’t have to worry about since you have plenty of time to update in the future.
