Apple You no longer sign iOS 12.3, 12.3.1, or 12.3.2 for your line of mobile devices on Wednesday night, a move that prevents users from recovering to a firmware version prior to iOS 12.4, which was released to the general public. only last monday.
That is unusual for Apple to stop signing old versions of iOS, especially a week or two after releasing new updates, but it's worth noting that Apple Stop signing at least three iterations of iOS in one motion this week, which doesn't happen too often.
The reason Apple to stop signing old versions of iOS is to promote software updates among your user base. By avoiding firmware downgrades, the company effectively ensures that users take advantage of the latest features and security updates. An unfortunate side effect of this scheme is that it makes recovering from the iOS version easier to jailbreak, though not impossible.
Apple The decision to stop signing iOS 12.3-12.3.2 tonight doesn't have much of an impact on the jailbreak community because the latest jailbreaking iOS version is 12.3 beta (which does not include public versions of iOS 12.3) With that in mind, jailbreakers have used iOS versions before, and the only way the current event could become a problem is if the same user needs to recover via iTunes for some reason.
If you currently use iOS 12.3-12.3.2 and are waiting for a jailbreak, so the best thing you can do is stay where you are. However, given all the recent exploit releases in memory, you're likely to admit that this version could become jailbroken in the future. Although that is not a guarantee by any limitation, the general rule suggests that the exploit possibility will be released for iOS 12.3-12.3.2 than for iOS 12.4.
For the record, there are legitimate reasons for lawbreakers to want to downgrade the firmware of their iOS device as well, as if the update introduces some kind of critical error. However, these cases are much rarer.
As always, you can monitor the status of the firmware signature for all your iOS devices with the IPSW.me online utility.
