Earlier today Apple mistakenly started signing older firmwares. This is a mistake and Apple will most likely correct it in the next few hours. This mistake, however, allows users to downgrade to previous iOS versions and even jailbreak their devices. The list of all the current and older firmwares signed by Apple is as follows:

iOS 11.2.2
