As usual, when a new iOS version is released, Cupertino’s signature stops signing the older versions in order to encourage users to install a much newer, stable, and secure edition of the operating system. Therefore, Apple announced that it has officially stopped signing iOS 11.4.1 .
This means that from now on, all iOS devices that are upgraded must install iOS 12 and the current version of iOS 12.0.1, as these are the only versions of iOS that the general public can install on iPhone and iPad.
Even developers and public beta testers can now download a higher version, iOS 12.1 , as this update is currently being tested.
Remember that it is always advisable to install the latest stable version available , because in addition to its new features, it brings bug fixes and security bugs. So if you haven’t updated yet, it’s time to move to iOS 12 or even better, to iOS 12.0.1.
