Further details about the jailbreak are scarce; we know however that it does support the iPhone 7, which is nice news for flagship device owners who were only partially supported by Yalu1011. It has been rumoured that the jailbreak supports only 10.3-10.3.1, not lower firmwares such as iOS 10.2.1 and 10.2, but this is not confirmed. Similarly, whilst it reportedly supports all 64-bit devices (implying not 32-bit) this is also unknown for sure at present. Certainly, the only thing the image clearly shows is that it runs on the iPhone 7 on iOS 10.3.1.
The initial Yalu jailbreak hype died down when Apple patched the necessary vulnerabilities with iOS 10.2.1 and above. At this point, there's no publicly available jailbreak for Apple's latest mobile software release, iOS 10.3 and iOS 10.3.1. However, if the latest piece of news is anything to go by, then it seems as though things are about to take a drastic turn for the better.
Pangu, the team responsible for the wonderful Pangu9 jailbreak, walked on stage at a conference and casually demoed an iOS 10.3 / iOS 10.3.1 jailbreak on an iPhone 7. The conference, which is taking place in the Mercedes Benz Arena, on Expo Avenue in Shanghai, appears to be called Janus.
I'm sure people have a lot of questions at this point regarding this jailbreak and which devices it will be compatible with. According to one source, the jailbreak will play nicely with 64-bit devices. That's pretty much the entire range of phones and tablets that can run iOS 10 out of the box. Also, it appears as though Pangu is aiming to release the iOS 10.3.1 jailbreak to the public some time next week, given everything goes to plan. At least that's what the source of this news is claiming.
Personally, I would recommend jailbreakers stay on your current iOS. Because there is a possibility that things can change drastically down the road. We have no word officially from Pangu itself, and every speculation at this point is like firing an arrow blindfolded.
