Rumors about the existence of an allegedly jailbreak solution for iOS 8.4 circulated for a while, but today everything changes. The well-known iOS hacker @i0n1c demonstrates in a video that Cydia works perfectly on iPhone 6 Plus running iOS 8.4. Music and Apple Watch applications are also presented to confirm that the jailbreak was made on the most recent version of the operating system and not an old one.
According to information provided by @i0n1c, he only needed 4 days to develop the jailbreak solution for iOS 8.4 beta 1. Also mentions that a public jailbreak solution is out of the question.
According to details, the vulnerability was discovered this year after a security conference held in Singapore, and there is little chance that Apple will ever block.
Although iOS 8.4 jailbreak is demonstrated, the hacker argues that this is not untethered, but at the moment it does not matter that much considering that this jailbreak solution will not be released to users.
