iOS version signing
How do we find out when an iOS version will no longer be signed? Is there a site that has this information with dates, etc? I've searched and can't find this info anywhere.
How exactly do you define "Signed"?
I have iPhone 4S iOS 9.3.6, iPhone 5 iOS 10.3.4, iPhone 6 iOS 12.5.6, iPhone SE (1st Gen) iOS 15.7, iPhone 8 iOS 16 and an iPad Pro iPadOS 16 and iPhone 12 Pro iOS 16. Prior to that, I had iPhone 3GS, which I have stopped using because it is carrier-locked.
All of them are still functional.
