A jailbreak for iOS 10.2.1 has been released, dubbed Saïgon. Made by Abraham Masri and using exploits from the famous developers: Ian Beer, Adam Donenfeld, and the infamous Luca Todesco.
The jailbreak has a catch, however, and that is that you need to run the app via Xcode. You cannot just push the .IPA file using Cydia Impactor as you would with previous jailbreaks for iOS. This may be a huge deal breaker, and we get that, however, expect a solution to this issue soon enough as soon as the project gets more developer interest.
The app is pretty straightforwards. Once you get it working trough Xcode, open it from your phone and just press jailbreak, as you would with the Yalu102 and the extra_recipe jailbreaks.
The good news for this jailbreak is that it supposedly supports all 64-bit iOS devices, which includes the iPhone 7 and the iPhone 7 Plus. Of course, as the iPhone 8 launched with iOS 11, don't expect that device to be jailbroken just yet. The jailbreak uses the KPP bypass used in extra_recipe which makes it compatible with Apple A10 Fusion-powered devices.
Even though you may not be running this firmware, and you might not know how to get this to work, this is very good news regardless. This proves once again that software can always, and will always be hacked. Users running other iOS versions should see this news as an encouraging event.
Passing on to you. What do you think? Do you run iOS 10.2.1 and did you succeed in jailbreaking it? Let us know in the comments below.
