InfoAll we know right now is that the Pangu team released a iOS 9/9.0.1/9.0.2 untethered jailbreak. Now while most people haven't tested this on iOS 8.4.1 (Considering it was just released today) we expect that if this is fully compatible with iOS 8.4.1 more tweaks will work for that version (WARNING I am not sure if this works on iOS 8.4.1, you will have to do your own research about that). Only a small amount of tweaks will work on iOS 9 and above. Maybe so after a weak or two most devs will have updated there tweaks. Good tweaking! StabilityRight now for most people the stability of this jailbreak is fine. On the new iPhone 6s most tweaks will not work. It is not recommended by me that you try using tweaks on the iPhone 6s that change the look of the screen. The reason for this is because since the iPhone 6s has 3D touch we have to wait for devs to update their tweaks compatible for the 3D touch feature. On the iPhone 6 through iPhone 4s it should be fine. You may correct me if I am wrong here.
