iPhone 4 Jailbreak (iOS 4.1): Download GreenPois0n before iOS 4.2 Update

By Alan Ng - Sep 25, 2010

We have some good news for the thousands of you waiting for an update on the GreenPois0n jailbreak tool for iOS 4.1 devices, as it has been suggested that Greenpois0n will be available to download before Apple push out the official update to iOS 4.2.

As reported from RedmondPie, the news has once again surfaced from Twitter as ‘Vince’, the guy responsible for maintaining the official iPhone Wiki website has posted the following tweet about the upcoming GreenPois0n jailbreak:

”They won’t wait for iOS 4.2 to release SHAtter. iOS 4.1 will be jailbroken soon.”

While this isn’t a confirmation as such on the release of GreenPois0n, this tweet was a reply which was distributed amongst iPhone Dev Team hackers.

The ball now firmly rests in the hands of the Chronic Dev-Team, who will be responsible for releasing the tool for public use. We’re not sure when Apple will release iOS 4.2 officially (it’s still in beta), but it is good news if GreenPois0n will be available before it.

Let us know your thoughts on this. Are you still waiting to jailbreak your iPhone 4 or new iPod Touch? Don’t forget that you can still jailbreak your iPhone 3GS/3G and iPod Touch 3G with the latest version of Sn0wbreeze.

  • Steve

    Plain stupid

  • Cory Lincourt

    I pre ordered my iPhone 4 and it came it in te second shipment it had iOS 4.0 factory. I've upgraded to 4.0.1 then 4.0.2 then recently 4.1. I've never jailbroken this iPhone before. Will I be able to do it with this jailbreak because it will be a first time jailbreak? Email me at Clincourt@me.com

    In a response to wasuup, I think the idea of unlocking the iPhone 4 4.1 ios is actually pretty exciting, and not for the sbsettings app and the like. Cydia has many amazing downloads, but most of us with iPhone 3G or 3GS or even iPad dont't like the fact that these apps slow our phones down so much (lack of memory). If I want to run sbsettings and backgrounder on my iPad with the same speed and without crashing whenever I open an app, I can't have winter board installed. I look forward to running a JB iPhone 4 merely because of the fact that it has the same 1Ghz processor as the ipad but double the ram, sitting at a hefty 512MB, and for a smartphone, that's amazing in itself. I look forward to being able to use all the great apps that I already have on a non JB iphone 4 alongside the great apps that make jail breaking worthwhile. It's reported that over ten million iPhone and iPod and iPad users jailbreak their devices. There's definitely a reason for it. These developers exist on cydia because apple won't put there incredible apps on the app store, even though apple is technically stealing their ideas and putting them in each upgrade. I don't like apple's policies, so as long as I can continue to screw them out of my money in the software department, I will. I anxiously await the next jailbreak release. Don't lose heart, guys. Keep it up, we all really appreciate the work you do.

  • Fadi

    Well just Another Guy waiting on Fire for the realere of jailbreak for iPhone 4 with 4.0.2 bought like this New i don’t Care for the unlock Cuzy Device is already unlocked only waiting for the jailbreak i Hope its Coming soon …..

  • George

  • steve


    "Wasuup" with your writings dude? "Wasuup" with the punctuation marks? And where the hell is your spell check

  • saravana

    i had erased all contents in my unlocked iphone 3gs running 4.01, done the erase because of some OS problems which is not working. and restored to 4.1 version. The screen got stucked after reboot showing emergency call and insert simcard with no pin lock to activate the iphone.

    Kindly help me or say how can we make the phone work, i need to unlock once again to use local network

    • John

      iOS 4.1 unlock is not out yet.. If you just want to get rid of the emergency call. I think you can get a sim card which is from the country that you got this phone, plug it in and activate it. I'm not sure is there any activate software for ios 4.1

      • steve

        You can get any sim card active or non active to get rid of the emergency call. Must plug into Itunes when doing this.

    • steve

      Sorry Saravana. Unless you are with ATT, there is nothing you can you. Even if your previous OS got saved through ssh, the fact that your baseband has been upgraded to 5.14, which is not a good thing. The current Ultrasn0w does not support; for 3G and 3GS highest baseband version is 5.13 and for Iphone4 highest version is 5.19. Sorry

  • Sophie

    Im so excited to jailbreak my new IPad 3g!! I hope they release it before october or maybe the first weeks of october! I so love my ipad now and i know im gonna be loving it more once its jailbroken!! My ios is 3.2.2 so im also checking out for greenpoison’s release everyday!! I dont wanna downgrade to 3.2.1 though..

  • abz

    hi ive got the iphone 4 with 4.0.2 and wanted to know if i should install the 4.1. if i do this would i still be able to jailbreak when it is released? whats the best thing 2 do? please help!

  • Saugat

    i Have 32 Gb Iphone 4( OS 4.0.1 ) and its Factory Unlocked Frm HKG…
    Can i update to 4.1 using another Sim…
    Its juss that i want it unlocked…so that i can use my sim…
    JAILBREAK is juss an option…

  • John

    I've never been jailbroken before and when i decided to jailbreak my iphone 4, It was already in 4.0.2. then i heard about the greenpois0n jailbreak and i'm just waiting for it. I check for info everyday.

  • Steve

    don’t update through Apple or your unlocked will get fucked. Ultrasn0w only works on baseband up to 5.13 for 3G and 3GS and 1.59 for iPhone4.

  • Steve

    don’t update through Apple or your unlocked will get fucked


    @wasuup.. worst spelling i've seen in a while.

    • ???

      hahaha read what he typed, i dont think he actually speaks english, probably using google translate… hahah

  • Changnoi

    There must be a hundred million people waiting for this jailbreak.

  • wasuup

    people who don’t have jailbreak on there phone should stfu because the iphone isn’t a paper weight without jailbreak also the only people who are genuinly p’ed off are people who download cracked app it cost not much to unlock the iphone and some of the best app are only 99 cent so the only geniune benifits are from jailbreak are facetime on 3g ifile and sbsetting so without them it not like death, but a defo thanks to all the developers who for FREE send out a jailbreak and apple I don’t believe they enjoy making anti jailbreak patches but have to because that would give developers of app in the app store a good reason to sue apple for not preventing the from being cracked and distributed with a loss to the developers income so just because of half a dozen cydia apps is not a nightmare I Love the iphone jailbreak or not it one great phone

    • Steve


    • hum

      Retard. Just go eat your aple

    • appalled

      dude… run on sentence much??? punctuation does not just mean commas.

      it's impossible to follow this thought, are you from the inner city?

  • Alvaro

    funny how people ask if they can upgrade to 4.1 to not look so stupid… we all know you already upgraded y'all. but good news… you probably will still be able to jailbreak and unlock

  • Ray


    there's no jailbreak out there for ios 4.0.2, hackers did not waste time on it simply because you can just install PDF patch on ios 4.0.1 and below. Even if there is, your baseband must not be updated for it to become unlockable using "ultrasnow". Meanwhile, if your phone is locked to tmobile and not to "AT&T" u can safely update to 4.1 without simcard, assuming that you are using tmobile as your official carrier.

    • Sarah

      i don’t understand. So can i upgrade to 4.1 right now? and just wait for the jailbreak? I haven’t even opened it.

  • Ray

    even if we say a lot of comment it doesn't change the fact that we still don't have the JB tool in our hand, so might as well be patient and wait for greenpoison to come, after all we had the word on from them to release it before 4.2 update.

    @Qasim, u can use a tool called "recboot" to kick your phone out of recovery mode.

  • Qasim

    iv got a 3gs 16gb new bootrom on 4.0.1 jailbroken (jailbreakme) and unlocked. i stupidly reset the phone from the phone itself (erase all content) and now its stuck at apple boot logo on start up. i dont have the shsh hash files, just checked. 🙁
    itunes wont let me install official 4.0.1 coz apple wont verify it (shift restore).. meanwhile ive left the phone in recovery mode so i have NOT updated to 4.1 yet.

    **can i update to 4.1 officially but still unlock/jailbreak …**

    please help me, genuinely in need of help as i rely on an unlock to use iphone. email qzeb@hotmail.com or reply here or watever, thanks alot guys. appreciate anyone hu can advise me what to do….

    • Man

      Yea, use Sn0wbreeze! Use it to create a custom 4.1 firmware.

    • Just use a program called Recboot, its free and you can run it to exit recovery mode to stay on 4.0.1 and wait for the 4.1 jailbreak to come out so you can upgrade.

  • Sarah

    so i bought my iphone and i realized it was 4.0.2. I am a tmobile user and i want to unlock it and jailbreak it. Can i upgrade to 4.1 without a sim card and wait for this jailbreak event?!?!

  • Jarson

    My iPhone4 has 4.0.2 factory as well, and I'm impatiently waiting and browsing websites looking for any infos. 🙁

  • gd224

    I'm waiting on my 8GB iPod Touch 2G (techincally I got a 3G) but its a 8GB, go figure. I have 4.1 and I wanna jailbreak, lets hope its this week before I go on vacation!

    • Nick

      u idiot you can already JB it with sn0wbreeze

      • gd224

        Actually, u cant, besides, I already did with jailbreakme! I rolled back to 4.0, then did it on there! So shut up!

  • Yeah, my iPhone4 was a factory 4.0.2 as well, my idiot gf thought she was doing me a favor when she updated it to 4.1… *facepalm*

    • Eugene

      same here. My friend gave me her 3gs and the night before she gave it to me she updated to 4.1 because she thought she was doing me a favor also. Waiting on new program to jailbreak and unlock this thing…now its just a paperweight.

      • anonymous

        forgive your GFs guys

    • Tyler Durden

      haha fuck your life.

    • Marla Singer

      your gf thought she was doing you a favor when she started dating an idiot like you…*facepalm*

  • biggie

  • Guest

    Still waiting to jailbreak my iPhone 4! Mainly because I need it unlocked.

    (factory 4.0.2)

    • yeah same here i sold my 3g jb and unlocked to buy the iphone 4 only to find out their was a shortage! when i fanally got one it came with 4.0.2 out of the box 🙁 i spend majority of my free time looking for greenpois0n updates

    • steve

      Same here! Need to unlock factory 4.0.2 It's weird the ipad is unlocked native but the iphone4 is not. =(

  • crck


  • M0Dx10

    Snowbreeze can NOT jailbreak 3GS with NEW bootrom! @author: edit u’r article please.

    • Philip

      it can be broken if previously jailbroken on 3.1.2.

  • Jamie

    I wish I could jailbreak my 3gs but i dunno if its old or new bootrom I just bought it and the guy restored it to 4.1 so i can't downgrade cause i don't have the shsh blobs on it or on cydia so im screwed right now. anyone tell me a 3gs 16gb white is old or new or is it impossible to tell?

    • michael

      ya umm you go into settings then general then about after that you go check the serial number if the 4th and 5th digits are over 50 (or 40 im not sure) then its the new bootrom

    • Philip

      Hey man I'm in the same boat. It sucks! The ONLY thing that I've read that will work is when they release greenpois0n. And hopefully that will be on the 27th. If you try anything else and it works let me know.

    • Dan

      Is it mc or mb

    • deral

      go to google and search for "iPhone2,1_4.0.1_8A306_Restore.ipsw"
      download it, save it to ur desktop. open up itunes… this prcess worked for me to downgrade my cousins 3gs to 4.0.1. if you know wat to do next then continue if not then contact me at deral(8)atGMAILdotcom. without the ( ) and u know the @and the dot part.

    • Seth

      Go to ih8sn0w.com. Download and run iDetector. It will let you know for sure. I have a refurb 3GS that says MB model with 34 in the serial, but I've confirmed it has the new bootrom with this tool and by using jailbreak tools (spirit2pwn) that work with 3GS old bootrom that failed.

    • Your Boy

      Use Snowbreeze 2.0 that can jailbreak any iphone besides 4….

    • Ben Dover

      you could jailbreak it with redsnow
