Avoid iOS 12 If You Jailbreak
If you still jailbreak your device(s), you'll want to avoid the iOS 12 beta and the official version of iOS 12 when it arrives.
Jailbreak developers have jailbroken iOS 11.1.2 and below, but we haven't seen anything emerge for newer versions of iOS 11 or the iOS 12 beta.
At this point, we'd be shocked if developers managed to release a public iOS 12 jailbreak on release day. To be safe, you'll want to avoid iOS 12 when it arrives.
Keep an eye out for iOS 12 jailbreak details before, and after, the iOS 12 release date.
