Apple is Still Signing iOS 18.2.1 and iPadOS 18.2.1, Downgrade from iOS 18.3 and iPadOS 18.3 Possible on iPhone and iPad

A new software update is out – iOS 18.3 and iPadOS 18.3 – but if you want to go back to iOS 18.2.1 or iPadOS 18.2,1, there’s still time to do it.

Currently, Apple is signing the iOS 18.2.1 and iPadOS 18.2.1 updates. And given how important iOS 18.3 and iPadOS 18.3 are in terms of bug and security fixes, chances are high that Apple will stop signing iOS 18.2.1 and iPadOS 18.2.1 very soon.
