Don't Install iOS 12.4.4 If You Jailbreak
If your device is jailbroken or you think you might want to jailbreak your device, you might want to avoid iOS 12.4.4 for now.
The iOS 12.4.1 update's sole purpose was to plug up a vulnerability that was used by jailbreak developers to exploit iOS 12.4. If you're running iOS 12.4 or below, iOS 12.4.1's patch is included in iOS 12.4.4.
Fortunately, jailbreak developers have released a tool, dubbed checkra1n, that works with newer versions of iOS 12. Unfortunately, the tool is in beta testing right now. We don't advise using it unless you're a power user or desperate.
Jailbreak developers have also released an official jailbreak tool for iOS 12.4 and that's probably the route you'll want to go until checkra1n leaves beta.
Note that checkra1n doesn't work for newer iPhone models. It's only compatible with iPhone 5s-iPhone X.
