Apple came up with a great idea rewarding users for finding iOS vulnerabilities. Thanks to this, Jailbreak software higher than iOS 11.1.2 is impossible at the moment.
It does not change the fact that many talented programmers “share” their discoveries, at least in the form of video.
On the latest video, you can see in action the Project Moon application required to perform Jailbreak iOS 11.3.1 directly on the Apple mobile device. An interesting, though doubtful addition is Cydia, which is not officially adapted to work with iOS 11.3.x. However, you can see that the author of the recording also runs the Terminal, so theoretically can download the plugin from Cydia.
The video at this moment certainly does not herald the release of the Project Moon application for anyone interested in making the Jailbreak. Fortunately, it shows that it can be done on the latest software and it seems to be a matter of time. The problem is that Cydia can be a serious problem and a decent alternative would be useful for her. I do not think Saurik would suddenly begin to share the source code of his application with whom he falls.
At this point, it is difficult to determine the date or probability of Project Moon release for users of Apple mobile devices. Before this happens, Jailbreak should appear on version 11.2 to 11.2.6 due to the Purple Smoke exploited. From pure curiosity, I will come back to iOS 11.3.1 on the iPhone 6 Plus and wait for the situation to develop.
