Turns out, the hype surrounding the iOS 9.3 jailbreak was to much for iOS hacker @enMTW so decides to sell the solution to China. He also complains about the jailbreak community, and the fact that is not getting any help from @Saurik (Cydia developer) to provide users with Cydia app.
Hacker recently claimed to have a jailbreak solution for the latest iOS version that wishes to release publicly for free.
In a published explanation on Reddit, hacker said that it was a huge pressure to release the jailbreak solution, but t is useless without Cydia, so he accepted less money only if it will be released publicly.
From this point no one knows how long until the Chinese buyers will give us an iOS 9.3.1 jailbreak solution, but it looks like it will come with Cydia and everything we need to enjoy an jailbroken iOS device.
