iPhone iOS 4.1: Jailbreak and Unlock – GreenPois0n Twitter hints

By Alan Ng - Sep 14, 2010

Following from the news that the next jailbreak solution on the iPhone 4 would also be available for the new iPod Touch and iPad, we can now confirm the name of the program that will be used to jailbreak iOS 4.1.

According to RedmondPie, the new method will be known as ‘GreenPois0n’ and will be supplied by the Chronic Dev-Team. For those who have experience in the jailbreaking scene, you’ll remember GreenPoison as the same tool used to jailbreak iPhone OS 3.1.3, as well as OS 3.2 for the iPad.

After a week since Apple pushed out iOS 4.1 to users, it looks like an iPhone 4 jailbreak tool is definitely on the way, here is a message that p0sixninja, a Chronic Dev-Team member posted on Twitter:

”Hey, @p0sixninja ‘s epic greenpois0n works well on iPhone 4G ! (need to work on the framebuffer code tho ! )”

Stay tuned for when the download goes live, in the meantime, give us your reaction to the news.

    Hi guys, Is there any process for unlocking I phone 4.1 version? I am queriously looking it
    Tell me ha

  • Hi every one

    If you have updated to 4.1 on 3GS

    Just check your bootrom or base band

    If you are 05.12.02 you just have to wait

    But if it was different here the good news

    Go to cydia/sections/go to the search and

    Look for fuzzband install it respring (reboot)

    On/off the you will see an fuzzband icon

    Run it and if you lucky you willbe laughing

    Enjoy ( greenpois0n works may be you have to

    Try it several time to get into DFu mood

    Good luck everyone

  • tbag

  • George

    new rumors from Limera1n that will release jailbreak very soon, just abut days left, and one more thing Milano, it is called 4G because it is apples 4th generation phone, it is not connected with cell

  • George

    waiting for greenpoison jailbreak release, i have iphone 4 ios4.1, my phone is useless like yours people, i am sure that it will be released soon, it wont be a problem, no way, someone will do that for sure, there are thousands of people like me, we wont be disappointed, NOTHING IS IMPOSSIBLE!

  • Alpe

    Hi, got a nub question here.

    After the jailbreak is here all the guys that need to unlock there phones must still wait for another update for UltrasnOw, because of what i've understand it just work with firmware up to 01.59? If so, when will they fix that?

  • Milano

    ”Hey, @p0sixninja ‘s epic greenpois0n works well on iPhone 4G ! (need to work on the framebuffer code tho ! )”

    Havent people by now know that it is Iphone 4 and not 4G?

    Its not 4G at all it still runs on 3G network.

    Just as an FYI.

  • tim

    IMPATIENT IDIOTS……. wait ffs…. dev team are incredible and will work on it… jesus… u guys are so impatient, yes i have a iphone 4 on 4.1 and yes im pissed but what can you do? you should have not upgraded to 4.0.2 or 4.1 anyway……. be patient and give them some credit……damn.

  • ihk

    i swear this people are retarded… YOU CANNOT JAILBREAK 4.1 YET. Wait for a week and it will probably be here.


    This is bullshit LIE ,i guess someone have nothing to do in their life sitting there scratching her or his whatever gender is 😉 writing crap and trying to be a writer LOL. THERE WILL BE NOT GREEN SHIT BUT I CAN GIVE YOU WHITE ONE 😉

    • Matt

      You are a total foreign idiot. Get your English straight.

  • IHateJail

    Must… Jail…Break… IPHONE…. 4.1 !!!!!!!!!!!

  • beau_beaumont

    will this work with the iphone 3gs on ios 4.1?


    NOT FAKE!!!

  • jjjddd

    hi is this real http://www.youtube.com/watch?v=LghYOPlo7pY. will it really work??

  • gunn

    i have read every post, but no one says if it is possible to unlock without jb ios4.1.

    is it???????

  • Mike

    The jailbreak for the iOS 4.1 exists and is out but really does not help because the baseband is 02.04.10 which requires a separate unlock. So is there a unlock in the works too? Ultrasn0w does not support the new baseband.

  • bthoven

    I heard that once you've updated your phone to 4.1, the new baseband will be there even you can downgrade the firmware to 4.0.x. So if you accidentally upgraded your phone to 4.1 without preserving the existing baseband, you cannot unlock your phone with the current version of Ultrasn0w.

  • Emily

    I really hope this will work on the iPad.

  • Mangina

    far out ITS REAL

  • p0sixninja

    This is real and it will be coming out soon! Have patience!

  • Vince

    This will probably dissapoint some of you, but if you bought a phone on 4.1 or accidently updated to 4.1 you wont be able to unlock your phone with the new jailbreak that will be release. Jailbreaking and unlocking your iphone are two different processes, and unlocking it will require that you jailbreak it first… but unfortunately, the current Ultrasn0w (0.93, tool needed to unlock your phone) can unlock all baseband up to 01.59.00 (OS4.0.x) and will not be able to unlock the new baseband 02.10.04 that came with 4.1… Therefore, the only way you will be able to unlock your iPhone 3GS/4 if you accidentally upgraded is if you have your SHSH blobs saved for an earlier FW than 4.1. Downgrading to that FW will automatically downgrade the baseband and you will be able to use ultrasn0w once your device will be jailbroken.

    • Matt

      You don’t know what you are talking about knob.

  • Cindy

    But aren't there safety chips installed that could in theory shut the iPhone down completely if it realizes you've changed something that shouldn't have been changed? Or just revert it back to normal? Though this would be my first jailbroken phone so I don't really know what I'm talking about.

  • pL@n3tPOX

    Just confirmed that the jailbreak is almost done but rumour from Apple is that a new update is planned to close this hole so most likely the jailbreak will not be released until after the 4.1.1 update.

  • Master

    How the hell can you "accidently" upgrade to a newer version, you have to be a complete idiot not to read the message saying that a new version has come out and DO YOU WISH TO UPGRADE, morons

    • KUPO

      think about the fact that some people have slow computers, possibly pressing the enter key as their itunes pops up when they connect their ipod not realising that was the active window. your the moron for not thinking outside the box. prick

  • Amit A.

    still waiting… =)

  • robOne

    I am very confident in you guys. You n the dev team have done it numerous times befor you guys are awesome keep it up I’m depending on you! so is a million other people (no pressure) LOL!! I don’t want to get involved with idiots who says you can’t do it but prove em wrong. Also if there’s been an unlock for every other firmware why not this 1!!!!

  • Neal

  • reply

    Could be fake why not bluff and say you can unlock all devices and get payed big time by Apple to stop you from doing so.

  • KUPO

    I hope this is real, jailbroke my 4.0 but then "accidently" upgraded to 4.1. DOH! lol kudos to those hard working people who make these jailbreaks possible! 😀 xxx

  • unknown

    i think charles has a ADD that's why he posted it..

  • dude

    ^^ i wanna jailbreak mine i have 4.1

    what do i have to do.

  • kravitz

    It better be released soon 🙂 can't wait!!! i love devteam!!!!

  • Ice

    Hi I’ve never jailbroken my phone, I’m on 4.1. When do you think this tool

    Will be available, also will I lose everything on my phone,

    What if I were to restore my phone to firmware 4.0.2

    • jon

      restoring to 4.02 wont do anything except loose you hdr photos and game centre.at present 4.01 is the only iphone 4 jailbreakable ios which unless you were on and saved your ssh file through cydia while jailbroken you can not downgrade to

    • Matt

      You will be able to restore with a backup ms have all of your contacts back. You can not restore to an earlier iOS. Apple and iTunes will no longer allow it. Read before you post.

  • Taste

    @Ice You can't restore your firmware to 4.0.2 because Apple stopped signing that firmware on Sept 9. Also, even if u could downgrade to 4.0.2, there is no Jailbreak for that firmware. Greenpois0n will be out soon I hope. No one really knows. maybe a few weeks maybe a month. And dont bother the iPhone Dev team or the Chronic Dev team because they are working hard on this. Let them work their magic so we can get the Jailbreaking goodness ASAP.

  • Vince

    Are you guys all retarded!? I you read only a little about this new shAtter exploit that will be used in the greenpois0n jailbreak, you would know that it's a bootrom exploit, meaning that no matter Apple releases a new firmware this exploit could not be patched (it will need a hardware modification, hence this tool would be able to jailbreak all iDevices FOR LIFE!). Read before posting stupidities like "does it mean shAtter is fake!?" or "the Dev-Team might save this exploit for the next firmware".

    • Jonathan

      I was wondering the same thing. Why would they delay this release when it would require a bootrom upgrade to overcome this exploit? No firmware upgrade could kill this jailbreak.

  • NICE! Let's get the framebuffer code down to the tee so we can jailbreak iPhone 5 even!

    • ampconsult

      hahaha, even iphone 5 we will unlock.

  • OnlyBlessed

    Yess!!! i thought hope was lost since i got the iphone fresh out the box with 4.0.2..i cant stand having a plain unjailbroken iphone lol

    • Al

      Yea I know wut ur sayin. I have a 4.0.2 iPhone 4 that is locked to US and I live in Canada. So no FaceTime or any other features. Hopefully the 4.1 jailbreak comes out before October. Thad be sick

      • tim

        fuck me dude tell me about it…..

  • Bryce

    The Cake is not a lie!

  • chuck

    this is real there will be many releases for this ios

  • Dogbolter

    there will definitely by a release for this latest firmware, is your head under a rock?? 4.1 jailbreak is inevitable, take a look around the web, its everywhere, just not out yet, will be soon enough im sure, cant wait….

  • reply

    and what is your source on that comment?
    Or is that just you hating?

  • Ruddy64

    And you know that how?

  • Cooper

    this is not fake. It is real but it may not be used to jailbreak ios 4.1, it depends wether they will use it now or save it for another jailbreak at a later date.

  • bob the builder

    there better be……I'm stuck on 4.1 after I realized the previous owner didn't save any SHSH blobs…….

    • lolroflmywaffle

      "there better be!?!?" -bob the builder

      u need to stfu and realize nothing is owed to u… these talented guys are doing it for free

      "I'm stuck on 4.1 after I realized the previous owner didn't save any SHSH blobs"

      nice try creating an excuse as to why u updated like a dumbass…..

      • bobthebuilderdick

        TinyUmbrella. search it up. faggot. and save ur SHSH. dont blame shit on the previous owner on things u cud've done. little dick faggot

      • Steve

        Your dumb ass screwed your own iPhone. The don’t have to release shit if they don’t want to. Ungrateful ass

    • Tonsa22

      I just want to jailbreak my Ipod Touch 2g v4.1, Tired everything, keep on getting errors.
      I purchased my Ipod Touch from flea bay. with IOS 4.1.
      Can anybody help me jailbreak this?

      (I have no previous shsh files)

      What about redsnow 0.9.5 beta 6 for Windows will this help?

    • Dragos

      Im stuck on 4.1 too 🙁 i keep my fingers crossed for THE guys worcking

  • Cooper

    this is not fake. It is real but it may not be used to jailbreak ios 4.1, it depends wether they will use it now or save it for another jailbreak at a later date.

    The dev team have jailbroke ios 4.1 and are currently working on the tool.

    • Matt

      Are u an idiot? Why would they save it for another jailbreak in the future? That doesn't make sense dude.

      • matt

        dumb f

      • erg

        If they find another simpler exploit, they’ll keep this one back, making the next Apple point upgrade a non-issue for the jaillbreakers (as they’ll already have the jailbreak code written). There appear to be at least two security holes identified, so it just depends on which group exploits which one for the 4.1 jb… the rest will be kept under wraps until 4.2+.

    • The hen

      They will release it for this version because it is a low level boot room jailbreak or whatever and it can only be fixed by apple by a hardware upgrade not software so all firmware updates are jailbreakable by this jailbreak. So there is no reason to wait.

  • charles

    this is fake there will be no release for this ios

    • toren

      really? shAtter is fake too? are you just speculating?

    • jake

      why would you say such a stupid thing?

    • John

      You're fake.

    • John

      Oh and Charles knows all LOL. Why would you even post something? Are you retarded? Why did you feel the need write something even though you were just making something up.

    • Thesam22

      It’s not fake… Ur the one who does not follow these guys in twitter

    • candice

      There is a release for it, I used the beta to start, *Big mistake, i freaked out my phone* But yes, they are working on greenpois0n to work on 4.1.

    • he is only a member of a PR agency hired by Apple to regulate discussion … old trick my friend !!!
