iPhone 7 iOS 11.4 Jailbreak MIA
Developers recently released an iOS 11 jailbreak though it comes with some caveats.
If you own an iPhone 7 or iPhone 7 Plus running iOS 11.1.2, iOS 11.1.1 or any other version of iOS 11, you should be able to jailbreak your phone today.
If you're currently running iOS 11.4, iOS 11.3.1, iOS 11.3, iOS 11.2.6, iOS 11.2.5, iOS 11.2.2, iOS 11.2.1, or iOS 11.2, you're out of luck. The jailbreak isn't compatible with those versions of iOS 11.
Unfortunately, we have no idea how long the wait for those versions of iOS 11 will be. It could be days, weeks, months.
Developers have reportedly cracked iOS 11.3, but there's no indication they'll release the exploit for the general public.
If you want to jailbreak your device, you need to be on an older version of iOS 11 or iOS 10. Unfortunately, there's no way to downgrade if you already moved to iOS 11.4.
