Apple is Currently Signing Various iOS 6 to iOS 10 Firmware Versions,
Downgrades Possible!

Apple opened the signing window for various iOS 6 to iOS 10 firmware versions today. It's unclear why or how long this will last so users looking to downgrade should do so ASAP.

Developer Steve Troughton-Smith tweets, "Not entirely sure why the signing window has opened for iOS 610 on various iOS devices, but not gonna complain. Have some iOS 6."

Currently signed firmware versions include: iOS 6.1.3, 7.0.3, 7.04, 7.1, 7.1.1, 8.0, 10.2, 10.2.1, 10.3, and 10.3.3. Unfortunately, the oldest version of iOS 11 being signed is 11.2 which means you still cannot downgrade for the iOS 11.1.2 jailbreak; however, those with an A7-A9 device may want to downgrade to iOS 10.3.3 for the G0blin jailbreak.
