Ο Winocm known from earlier jailbreaks, posted via Twitter, a video showing the first one untethered jailbreak of iOS 7.1.1 in one iPhone 4. According to the description of the video on YouTube:
Oh yeah, this is iOS 7.1.1 untethered if you didn't notice earlier. (iPhone 4 GSM though, don't want to mess with any other devices that I have. Would work elsewhere… if you put in the effort. ジ)
Yes, this is the untethered jailbreak iOS 7.1.1 if you have not noticed. (on iPhone 4 GSM though, I did not want to do it with any other device I have. I will do it elsewhere… if you contribute to the effort. ジ)
With iOS 8 coming soon, it is unlikely that hackers will release a javabreak tool for iOS 7.1.1 as they reveal the security gap they discovered. But it is encouraging to know that the jailbreak community is alive, and continues to look for exploits that can be used in future jailbreaks.
