Apple Stops Signing iOS 15.3 Following iOS 15.3.1 Release, Downgrading No Longer Possible

After the release of the new version of the software on February 10, Apple stopped signing the previous version of the software. It is not possible to upgrade to the newer version of the software if you have updated to the newer version.

After new releases come out, Apple stops signing older versions of software in order to encourage customers to keep their operating systems up to date.

There were two bug fixes in the 15.3 update, one addressing a significant Safari bug that could leak browsing activity, and the other addressing WebKit vulnerabilities.
