Saturday evening security researcher Stephan Esser also known as @i0n1c on Twitter posted a photo revealing a jailbroken iPhone 5c, which could indicate that an iOS 7.1.1 jailbreak has been achieved.  

However, the possibility that the iOS 7.1.1 jailbreak will go on public might be slim. Although, Esser has been an active contributing member to the jailbreak community, it is possible that he used something like a signed app to achieve his jailbreak, which makes it unusable to the public.

On the other hand, the jailbreak remains interesting as it appears to use newer exploits than modern jailbreaks usually employ. Esser claimed that, "

The jailbreak is, however, somewhat interesting in the fact that it seems to use newer exploits than most modern jailbreaks typically employ. According to Esser, "That iOS 7.1.1 jailbreak is not based on a long vulnerability chain. It uses a single beautiful kernel bug that goes from mobile to kernel."

However, when questioned by @MuscleNerd, Esser explained that jailbreak was not achieved as simple as it initially sounded.

"The untethering part is a separate bug. I was speaking about no complicated chain of tricks to break out of sandbox first then work around the mounting problem, I just use a plain and simple mobile to kernel exploit that can disable all sec features and works from any container."

Thus far, even though Esser's iOS 7.1.1 jailbreak will not go to public, its existence indicates that an iOS 7.1.1 jailbreak for the public is highly possible and there is a chance that we will be seeing the jailbreak anytime soon.

According to Esser, he is currently working and searching for solutions to make the iOS 7.1.1 jailbreak public.

Coincidentally, shortly after Esser's tweet, a different hacker known as @Winocm also revealed an iOS 7.1.1 jailbreak on an iPhone 4, which is an older device that is still jailbreakable. He noted that the solution might be ported to newer iOS devices if someone is willing to "put in the effort."

Meanwhile, it is interesting to see how other jailbreak developers would react to Esser's iOS 7.1.1 jailbreak.
