Apple routinely stops signing older versions of iOS after new versions are released to encourage customers to keep their operating systems up to date, so it’s not unusual for the iOS 16.3 update to no longer be available. signed.

iOS 16.3 was a relatively minor update that introduced support for physical security keys for Apple IDs, expanded Advanced Data Protection globally, added support for the second-generation HomePod, and more.

While iOS 16.3.1 remains the current public version of iOS, Apple released the first beta of iOS 16.4 last week with support for new emoji characters, web push notifications, and more.
