In this video, we have an important announcement. While the API developed by m1sta for fetching the signed Betas was broken for a few days, iOS 15.3 RC remains signed. This means you can still save the blobs or downgrade to it using FutureRestore. Aside from this beta, only iOS 15.4 is also signed which is not vulnerable to known bugs at the moment so it’s bad for jailbreak.
iOS 15.3 RC is vulnerable to the kernel vulnerability posted by Synacktiv a week and a half ago. If turned into an exploit, that can be incorporated into Taurine and Unc0ver Jailbreak to update them all the way up to iOS 15.3.1, at least for some devices. This is your last chance to downgrade before Apple unsigns it.
