Apple has stopped signing iOS 18.2, meaning iPhone users who have upgraded to iOS 18.2.1 can no longer downgrade to the previous version. This change came after Apple released iOS 18.2.1 earlier in January.
Typically, when Apple releases a new iOS update, it stops signing the previous version after a week or two.
This prevents users from installing older versions, as Apple’s software verification check ensures only the latest signed version can be installed.
The iOS 18.2.1 update includes unspecified bug fixes, while the now-unsigned iOS 18.2 introduced new Apple Intelligence features, including Image Playground, Siri ChatGPT integration, and Genmoji.
By halting downgrades, Apple ensures that devices stay up to date with the latest security improvements.
