Untethered Jailbreak iPhone XS on iOS 12 via Pangu Team - The Chinese iOS 12 jailbreak Pangu Team demonstrated jailbreak iOS 12 on the example of the iPhone XS.
This is a great achievement, especially given the fact that this device uses a completely new processor A12 Bionic, which is surely implemented improved protection against hacking the operating system.
iOS 12 has already been hacked, but the previous jailbreak was created by IS-specialists from Alibaba (it's the owner of AliExpress). They are unlikely to share their findings with the community, and the Pangu team is just specializing in the release of tools for jailbreaking.
Most likely, in the near future Pangu will release a program with which you can break iOS 12. We can assume that it will be compatible not only with the iPhone XS, but also with the iPhone XS Max, XR and earlier models of the iPhone.
