German iOS hacker Stefan Essar aka i0n1c has just shared a video on his YouTube channel. In the video, Stefan shows an iPhone 6 running on iOS 8.4 beta 1 Jailbreak Preview 1. To prove, he shows the Cydia icon right there on the home screen of the device. He also flaunts the Apple Watch native app, new music app and the eMoji keyboard which comes pre-installed in the latest iOS version.
Along with the video, he has also shared a note saying the iPhone 6 device is running on iOS 8.4 beta 1 JailBreak.
He then mentioned: "The major vulnerability used in here was found right after the SyScan 2015 security conference when I was relaxing in Singapore from several weeks of training and conferences. The vulnerability itself is however not new to iOS. Instead, it is inside the code virtually forever. But the code of this jailbreak has nothing at all to do with the previous CyberElevat0r for iOS 7.1.1 - it does not share a single line of code. I am not showing persistence or an untether at the moment because something is broken with it. But hey this is just a first proof of concept."
For preventing the Jailbreakers, Apple has been consistently patching vulnerabilities for quite some time now. In iOS 8.2, Apple successfully patched CVE-2015-1062 alias MobileStorageMounter to block TaiG from developing further Jailbreaks. With iOS 8.3, Apple has successfully patched 39 more vulnerabilities including the CVE-2015-1087 for preventing TaiG again.
Though i0n1c developed the Jailbreak, he has not mentioned anything on the availability yet. So, if you're looking for further Jailabreaks of iOS 8.2 or iOS 8.3, we recommend you to wait some more time till TaiG, Pangu or any new developer releases the update.
