So it’s looking like, when all is said & done... we’ll have 3 different jailbreak tools for iOS11-11.1.2. The one that’s already out from @Morpheus called “LiberIOS” and coming shortly we’ll have the one from @cheesecakeufo and the one from @coolstar, the developer of the theming app, Anemone.
We’re all just waiting on Saurik to update Cydia and Cydia Substrate.
I’ve already jailbroken with the LiberIOS tool because even without Cydia it protects your phone from auto firmware updates aggressively pushed by Apple.
This jailbreak will be another semi-untethered (side load) JB like we had for 9.3.3 and 10.1.1 and 10.2. You need Cydia Impactor to load the IPA file onto your phone.
