Greenpois0n for iPhone 4 & iOS 4.1: Download Now

By Jamie Pert

If you have been experiencing problems with Geohot’s Limera1n jailbreak we have some good news for you, the ChronicDevTeam has today launched the Greenpois0n jailbreak for iPhone 4 and iOS 4.1.

They revealed this in a tweet earlier today, sadly only the Windows version is up at the moment, however there is a Mac version being developed which will be coming soon.

You can download the Greenpois0n jailbreak here, the download itself is just 347kb in size and contains one exe, you can see a screenshot from the app at the end of this post.

The Greenpois0n jailbreak works with iPhone 4, iPhone 3G S, iPod touch (4th and 3rd Gen) and iPad, if you are using Greenpois0n on your iPhone 4 running iOS 4.1 you must use TinyUmbrella (here) to preserve your baseband.

Some early users suggest that Greenpois0n does not work, therefore we would appreciate your feedback in the comments section below.

Did Greenpois0n work for you? (Please state what device you was using and what Windows version you are running).

  go to general on settings and click about scroll down to modem firmware and if it is 05.13.04 or lower then install the ultrasn0w repo on cydia and install ultrans0w and bingo if not you can check out b0unty this guy released a fake unlock last time but has sent me a taster and it worked

I'm using ipod touch 3G with iOS 4.1, and now i'm able to jailbreak my ipod touch and installed cydia… i didn't swich off my device as it says on its home screen but follow the pressing buttons like it says on the following screen…. Thank you Jamie Pert…
- jamie
  
  How did you do it? I have an ipod touch 3g and 4.1 firmware but it cant detect the ipod is in dfu mode.
  - adalricus
    
    Once you open Greenpois0n, it says "please power off your device and connect it to begin", don't switch off your ipod touch.. but then, it'll ask u to press/release the buttons.. i just followed that (except switching off)… and my itunes popped up with saying that "detected recovery bluh bluh bluh", i just ignored (didn't touch anything) on my itunes… it took couple of minutes inbetween switch on and off again, but finally loaded with white icon "loader" which installs cydia and voila…. Good luck….
    - Jerry
      
      what do you mean "except switching off? " when i do it my ipod is not turned off but it still TURNS OFF because im holding the sleep and home button down for the time it tells me to hold it and it never works what do you mean by not switching off? thats basically the whole process

krip

iphone 3GS new bootrom iOS 4.1 windows xp tried greenpoison rc3 thrice and still not jailbroken .A blank loader app icon shows up from where i was able to install cydia but it wont open.
Tried both on and off methods of connecting the iphone before opening greenpoison.
- salaammaker
  
  this happened to me too. everything worked until i installed Cydia. Cydia is blank and once I click on it, it immediately closes. this seems to be the only problem.
Wubes

rex

if you get the error message "try again" and greenpois0n is not detecting the dfu mode, try again and make sure on the last step to release the power button beforee the iphone turns on again..or just make sure you follow the second countdown just as the program asks u to
Lily

Works perfectly on iPad 3.2.2. Make sure you have iTunes 10 and that it is open when you do the jailbreak.
- frank
  
  great stuff! seems to work for me, too. Ipad 16G wifi on 3.2.2 with windows 7. I have itune 10.0.1 and it was on when I run greenposion!!!!!!

Mark

Greenpois0n is not working on iphone 4 4.1(8B117). Ive tried both Windows XP and 7. Not too sure whats going on. Ive also tried Limera1n which is not working either.
salaammaker

I'm using iphone 3GS, 4.1 ios and found that the jailbreak worked until I installed Cydia. It's just a blank icon on my phone. When I click on it to load, it starts then immediately closes again. Help?
Jens

Had the same problem with Greenpois0n telling me that jailbreak failed and I had to try again.

Downloaded limera1n instead.

Turned on iPhone, open iTunes and started limera1n, followed the on screen instructions.

First shot, iPhone 4 with iOS 4.1 jailbreaked, now with Cydia and Installous running. Worked like a charm.

Shitty greenpois0n!!
Levi

it works for me 3 times already with different idevices….2 ipod touch 4gen and 1 iphone 3gs 4.1…
laika

ipad 3.2.2 windows xp greenpois0n cannot see ipad in DFU (windows does)
ipad 3.2.2 linux, greenpois0n shuts when ipad enters DFU
TheDood

used Greenpois0n to jailbreak 3gs with new bootrom but seems to be a little laggy when opening/using apps and moving around in the OS.
malcolms

I just tried this on my new iPhone 4 with 4.1 firmware and it worked like a charm, also, I made sure to backup my .shsh files first with TinyUmbrella.
Brinley Ang

Greenpois0n did not work for me on 3GS 4.1 new boot rom. Took a couple of attempts to get it to detect the phone in dfu mode, seems like I needed to follow the prompts exactly to the seconds to get it to recognise dfu mode. When it finally got recognised, it finished the jailbreak successfully but I couldnt find cydia anywhere? Anyway, tried limera1n and it worked successfully on first attempt.
ob1

Tried GP 51 Times now thinking i must be getting timing wrong using iphone 3g 4.1 maybe this should be renamed as greenpish!
FailJailbreaks012

i have a itouch 3g on 4.1

limerain-said sucessfully jailbroke but no limera1n icon

greenpois0n-keeps saying try again

both dont work for some reason
Nate the Great

I have used every Jailbreak that has ever come out on my iPhone 3G 8GB; however I tried this on a 16GB iPhone 3G and neither limera1n nor Greenpois0n worked on neither Windows XP or Mac OS X ver. 10.5.8 platforms. I download on Mac and it did not even work. On Windows it went through the start up but not in the DFU mode. In other words some is wrong here.
Brian Burwell

I have windows vista and a second gen 8gb itouch. The jailbreak went great. I was worried at first cause the begging screen looked like what i had seen from bricked itouche's but it actually turned out to have less bugs than jail breakme.com. So id give this a five out of five for jailbreaks.
Jaks

Had no probs jailbreaking my new Iphone 4 with Greenpois0n but my 3G 8gb one I gave the gf only gets a try again message. DFU mode is there but keeps saying the phone is not off. Try Again

Guess i'll just add to the list of the same question lol..

You guys that are freaking out and being azzheads need to chill a bit. A solution will come.
