After the arrival of iOS 17.2.1 a few weeks ago, Apple has decided to stop signing iOS 17.2 for the iPhone.
Apple has stopped signing iOS 17.2, the second major update to iOS 17 that was released on December 12, full of new features and solving up to 10 important security errors. Just a few days later, on December 19, Apple released iOS 17.2.1 fixed some problems and bugs, an update that It is the only one you can install right now.
Apple has stopped signing iOS 17.2 and you will only be able to install iOS 17.2.1 in case you are on an older version or need to restore your iPhone. Apple stops signing older versions of software so that its users are encouraged to have the latest updates installed and prevent them from having an operating system with security errors and less stability.
Consequences of unsigning iOS 17.2
That Apple stop signing a version of iOS means you won't be able to install it on the iPhone, not even if you try to force it. When you go to install a new version of iOS on the iPhone, the device first connects to Apple servers that must verify the software and approve the update, what we know as “signing.”
Having an iPhone updated to the latest version guarantees you can access the new functions or interface changes that the company has implemented in the system. Ensuring a better performance on the device and a good usage experience for the user.
iOS 17.2.1 has the same new features that came with iOS 17.2among which are the Diary app, new widgets and improvements in several applications, but adding to the correction of various security errors.
It is recommended that all users install this update as it includes important bug fixes.
