Thanks to CTOnews.com netizens for being reduced to a beautiful clue delivery! CTOnews.com, November 2 (Xinhua)-- Apple has now turned off signature verification for iOS 17.0.3, which means that iPhone users who have upgraded to a higher version can no longer be downgraded or restored to iOS 17.0.3 via iTunes or Finder.

Surprisingly, Apple continues to provide validation for iOS 17.0.2. In addition, Apple stopped validating iOS 15.7.9, iOS 16.7 and iOS 16.7.1.

Over time, Apple will gradually stop providing authentication for older versions of iOS to prevent users from downgrading to older versions of the software. Currently, iOS 17.1 is the latest version of iOS available to the public, while iOS 17.2 is currently in public beta and is expected to be released in December.

As previously reported by CTOnews.com, the latest iOS 17.2 version includes many feature updates, such as notebook applications, collaborative Apple Music playlists, Action Button translation options on iPhone 15 Pro, iMessage contact key verification, additional weather and clock widgets, etc.
