Apple recently released iOS 18.3.2, and as usual, it has now stopped signing iOS 18.3.1, making downgrading to that version of iOS no longer possible.
The iOS 18.3.2 software can be downloaded on compatible devices over the air by going to “Settings” -> “General” -> “Software Update.”
The iOS 18.3.2 update included important bug fixes and security updates.
Most of the issue was addressed with iOS 17.2, but Apple added an additional supplementary fix in the update.
Apple says that it is aware of a report that the vulnerability may have been exploited “in an extremely sophisticated attack against specific targeted individuals.” It should be noted that these attacks happened prior to iOS 17.2.
The issue was addressed with improved checks to prevent unauthorized actions.
On some devices, the update also fixed an issue that could prevent playback of some streaming content.
While falling back to an older iOS version is often used by users who jailbreak their iPhones, it can also be helpful for users who experience significant bugs after upgrading to the latest version of iOS.
By preventing users from downgrading their devices to older versions of iOS, Apple ensures that the devices are kept up to date with the newest security improvements.
