The just released iOS 8.4 beta 1 firmware has been jailbroken by Stefan Esser, also known as i0n1c.
The security researcher posted video proof of his jailbreak to YouTube earlier today.
----- Hi fellow netizens,
today I am delighted to share this video of a proof of concept iOS 8.4-beta 1 jailbreak that I was working on the last 4 days. Of course this video will trigger haters all over the jailbreaking scene that for some reason believe they can decide what a person is allowed to do or not do with their work. Haters gonna hate. So just ignore the haters and never let them tell you what you have to do. In that regard never let anyone bully you and stop you from showing your own hard work. Peace!
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 todo 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. -----
I0n1c also tweeted the photo below saying, "It is holy Sunday so let me leave this here as a starter ... #iOS_8_4_jailbroken."
While its good news to hear a jailbreak for iOS 8.4 is still possible, i0n1c hasn't released a public jailbreak since iOS 4.3.1, despite having successfully jailbroken morerecent firmware versions.

IF YOU CAN PROOF US THAT THE JAILBREAK WORKS, THEN U CAN SHOW US 'HOW' ??
???????????????????????????????????????????????????????????????????????????? RIGHT????????
Jailbreakios8.234? u joking? How about to learn how to write the codes or how to write a jail breaking program before you start demanding people what to do.
We all know i0n1c is unlikely to provide a jailbreak for the general public. This preview is as he put it, purely for his proof of concept and behind the scenes security research work. What it does bring to the general public is that it is, as it always is, possible, and hopefully someone else will figure it out so that way it might make it to the end user so we may enjoy the tweaks and modifications we have become accustomed to rely upon in our jailbroken iPhones.
they always jailbreak the betas first. one step at a time. no one would release a jb if the iOS was still a beta. that's just straight up stupid. it will get released when they drop 8.4. and @i0n1c is a genius. I do follow him on Twitter. he's a smart dude.
People aren't hating...people are scared that apple will patch premature jailbreak exploits. But still takes talent no matter if he shares exploit or not
This guy tries to impress the world by show off, we would be extremely happy if he releases a working jailbreak in future. Im not sure of this jailbreak, sine its beta1, apple might patch up these exploits in next beta or in the final build, as they did with ios 8.2. We can just hope an ld pray that some team really release ios 8.2 > line up.its been really worst phase in my iphone using history, using an iphone without jailbreak is so sad. I hope we might see some progress very soon.
