Apple stops signing support for iOS 17.3, encouraging users to keep their systems up to date

Apple announced that it will stop signing support for iOS 17.3 version, which means that users who have upgraded to a newer version can no longer downgrade to iOS 17.3. This is a measure taken by Apple to ensure that the operating system of user devices is kept up to date and to improve system security.

Apple released the iOS 17.3.1 update on February 8, which mainly fixed some text-related errors. The rollout of this update resulted in iOS 17.3 being no longer signed and certified by Apple, limiting the possibility of users downgrading to that version.

As far as I know, iOS 17.3.1 is currently the only publicly released version. However, Apple has not stopped updating and they are conducting beta testing of iOS 17.4. It is expected that the official version of iOS 17.4 will be released in March this year, bringing a series of new features to users. These new features include app sideloading (EU only), podcast improvements, and new emoji expressions. Users can look forward to experiencing more interesting and useful features in future updates.

Apple’s iOS 17.4 version will allow iPhone and iPad users to download and install applications through other app markets, which will bring more choices and convenience to users. However, Apple also reminds users to be wary of this feature because it may bring new security risks to devices and personal data. While Apple strives to reduce these risks, it cannot completely eliminate them. Users need to be cautious when using other app markets and ensure that the apps they download and install come from trusted sources.

Apple CEO Tim Cook has made it clear that for sideloaded applications, he recommends users to choose Android phones. The remarks underscore Apple's firm stance on system security and user experience.
