PurpleSmoke is an exploit that can allow the development of a solution to jailbreak for iOS 11.2, it being compatible with all versions released by the Apple company up to iOS 11.3. We are talking about an exploit that was kept until iOS 11.3 was released in the hope that it could also exploit this version of the operating system, but it seems that it is limited to iOS 11.2.x, unfortunately.
PurpleSmoke is currently only an exploit, not a software that allows you to jailbreak an iPhone for iOS 11.2.x, but after a complex development process it will be transformed into a real jailbreak. No one knows how long it will take to create such software, or if it will even have Cydia in an official version, but it is taken into account.
PurpleSmoke Exploit for iOS 11.2 Jailbreak Revealed
At the moment there is jailbreak for iPhone and iPad up to iOS 11.1.2, but beyond this version there are only exploits and hopes, but nothing else for users around the world. This PurpleSmoke exploit can be a solution for users who are waiting for a new jailbreak for iPhone and iPad, but for now it's hard to say how much patience the world needs to have.
"Alright, according to siguza it was patched in the macOS version that came out the same day as 11.3, I think iOS 11.3 won't be supported and made a huge mistake thinking it would be."
If you still have iOS 11.2.x on your iPhone and iPad, then I recommend that you wait for the release of a jailbreak solution based on PurpleSmoke, and if you have iOS 11.3, I recommend that you downgrade while you still have the opportunity to do so.
