unthreaded jailbreak

Make sure you read that title very carefully before you get too excited. Yes, there’s a new jailbreak out, and yes, it’s untethered. But odds are, you’re not going to fit its compatibility requirements. It only works for CDMA versions of the iPhone 4, and the app only runs on Linux.

It’s called UnthreadedJB, and it’s developed by a group of people under the same name. To be fair, this is the first untethered jailbreak we’ve seen for iOS 5.1—I believe Absinthe 2.0 was for iOS 5.1.1—so it doesn’t come without acclaim. And several users have confirmed that it works…

The group has been teasing the jailbreak for a while now, and has of course been accused of faking their progress. But upon releasing it today, several users and prominent members of the jailbreak community have confirmed it’s legit. Here’s a tweet from developer/hacker winocm:

The good news is, it’s untethered, so that means you don’t have to worry about hooking your device up to a computer after every reboot. The bad news is, it requires that you meet a very narrow set of standards. You have to have a native Linux computer, and an iPhone 4 on iOS 5.1.

If you live in the US, CDMA-only means your iPhone 4 has to be on either Verizon’s or Sprint’s network. And since you must be running on 5.1, that also means you would have to have avoided upgrading your firmware since, what, early 2012? What are the chances these days?

The upshot here, though, is that these guys also say they have a working untethered jailbreak for iOS 6.1.3/4 as well. There has not been a new jailbreak released since Apple killed evasi0n with iOS 6.1.3, and there’s not expected to be another one until after iOS 7 lands this fall.


At any rate, if you meet the current UnthreadedJB requirements, go for it. You can download the binaries and get started.

Thanks John

      they wanted to prove there not fake and get people to believe they got a 6.1.3/4 kernel exploit

      • Connor Hay

        I actually believe that they may have something but who knows, the evad3rs guy says that they can actually spell.

      • it was a troll all along guys

  • makedonii

    And how does this benefits us “users/jailbreakers?”

    Im not being douschebag, but who runs 5.1 at this point? All the 5.1.1 are satysfied so why care about this? Unless it helps 7.0 jailbreak, witch i doubt it :/

    • Gavin

      the guy claims to have an ios 6.1.3/4 and ios 7 kernel exploit for a untethered jailbreak

    • Jimothy

      It might. Maybe they found a long standing bug or kernel exploit of some sort.

      • Rocky Racoon does actually work on 5.1, it just was never tested on there and therefore Rocky Racoon didn’t support it. (This is my understanding, at least, but it does definitely support 5.1.)

      • Jimothy

        I was being really hopeful. It would suck if they just applied Rocky Racoon to it

    • Why not release the jb? There’s no use not releasing the tool they worked on.

      • Connor Hay

        they dont want it to get patched on ios 7 so that they do less work.

  • Kyle

    I really really really hope this is to prove that somewhat useful and usable tools can come from people other than the main jailbreak developers.

    Ermahgerd, dat camera effects… =_=

  • steve00000

    things that made me wtf:

    the damn music
    the shitty camera effects
    the tatty usb cable (ok a small one lol)
    ‘stoner guy’ reflection

    the purple bong
    the ‘sample text’ message showing multiple times

      I didn’t notice it at first, but it is meant to be a joke, and take the piss out of all of those fake websites which offer to jailbreak your iPhone.

      I figured it out when I went to their website and saw this: “We desgin HTML god right? 🙂 :)” whereas the website doesn’t even have a tag

  • Andyxyoona

    When this popped up in my News Feed. I thought: “Wait. I thought it’s 2013. Why am I getting 1 year old+ news here” *Click on it* Oh wait. WTF :/

    • that just happened to me. sadly mine was a bit more realistic at that

  • scaru

    I just would like to say that I highly doubt that this is CDMA only. It seems to repurpose a lot of code from the evasi0n jailbreak.

    • Jimothy

      Agreed. However I can’t get it to work. I don’t know why. Ugh. And I mean at all.

  • Jimothy

    Sorry, but I can’t get it to work. I don’t know why. Maybe it’s because I dual-boot?

  • CPVideoMaker101

    Dammit, I can’t downgrade to 5.1 ._. I use 6.1.3 😛 ~ iPhone 4 CDMA User

    • (JailbreakQA) King Shoot

      Yo Dingo, how come I never noticed you on this thread before?
      This is one of my all time favorites, a 5.1 JB in 2013 😛

  • abdullah575

    iOS 6 ??

  • Nice, but doesn’t prove trustworthy; this could be the start of Malware appearing in the jailbreak community. As I have no second iOS device, will live it to others to beta test it.

  • JaeM1llz

    How can they know enough to develop a jailbreak but be SO BAD at video editing?

  • they have a really weird website.

  • Winski

    And WHY is this important 2 YEARS LATE ???

    Back to the drawing board for you.,,,..

    • Tony Klapatch

      Only 1 year late!

  • ConduciveMammal

    Seems like a bit of a wasted effort. I can’t imagine there being that many people left of IOS5.1 nowadays

  • marcus1324

    Yes finally an untethered 5.1 jailbreak!!!!

    – Said no one ever

  • Joe Benning

    Sorry. You iP4 guys can have it. This and your bootrom exploit. I have two of them in my house and the GUI lag due to lack of RAM is horrible.

  • Ahmed Fayez

    Nice but toooo late

  • rasengan720 .

    This post jus formed a question in my head.. Does this mean that jailbreaks like redsn0w and evasion only work on gsm iphones and not cdma iphones?

    • Arjan Vlek

      No, they always worked with all verslons of the iPhone 4. Even the tethered 6.1.3 jailbreak doses work on the cdma version

  • Andyxyoona

    So apparently they released a iOS6.1.3/6.1.4 jailbreak today O__O

  • THREĘ 33

    Well that’s stupid just Linux , fuckin dorks pod2g and musclenerd !!

  • (JailbreakQA) King Shoot

    The most pointless of all jailbreaks
