Apple has effectively stopped signing previous iOS 12.3 versions and below with the wake of 12.4 release, which prevents people from downgrading once they update to iOS 12.4.
The Cupertino-based firm normally shuts down signing weeks after a new version of the iOS is released. When this happens, iOS users will no longer have the option to revert to the previous iOS via iTunes. Downgrading is often a possible solution for those who are experiencing bugs, but there’s also a large percentage of people who do this while waiting for jailbreak releases.
iOS 12.4 was released last week following the upcoming Apple Card feature. Yesterday, Apple CEO Tim Cook confirmed that Apple Card is on track to be launched in August. Currently, only Apple employees and Goldman Sachs executives have access to the innovative credit card.
iOS 13 beta is also being tested with a release timeline of somewhere around September.
