UPDATE: It on iOS 7.1.2 as well!
Today a team of Chinese hackers have released an untethered jailbreak of iOS 7.1.1. The utility is called Pangu.
Currently a jailbreak utility is only available for Windows users.
The team credits famous hacker i0n1c, who introduced the infoleak bug during his training. By the way i0n1c has said, “if pangu team releases a public jailbreak with vulnerabilities disclosed to them during my training I consider this in no way okay.”
