Peter Binder Few days ago we have informed you, that the limera1n jailbreak by Geohot has been released for most iOS devices supporting iOS 4-4.1. The article stated, among other things, that the Chronic Dev Team was also planning to release its jailbreak. He recently released greenpois0n.
Greenpois0n is essentially no different from Geohot's jailbreak. It uses the same exploit. Originally, before Geohot released limera1n, the Chronic Dev Team planned to release their jailbreak, which would be based on the shatter exploit. Or if it uses a security hole in the used A4 processors that we find in the latest iPhone model.
But Geohot released limera1n unannounced, so it would be pointless to release a jailbreak with a shatter exploit, because Apple could patch two security holes in the next version of iOS. Therefore, the Chronic Dev Team decided to use the same exploit as the one used by Geohot. So it is up to the user which of the two selected jailbreaks to use.
Greenpois0n supports these devices:
- iPhone 3GS,
- iPhone 4,
- iPod touch 3rd generation,
- iPod touch 4rd generation,
- iPad.
Greenpois0n can be done by users on windows and linux operating system. So even the Chronic Dev Team hasn't released a Mac version yet, but they also promise that we should see it soon. How to jailbreak? We will show this again in the following tutorial. The procedure is again very simple.
We will need:
- Computer with windows, linux,
- iOS devices,
- iTunes.
1. jailbreak download
Open a web browser and enter the address: www.greenpois0n.com. Depending on your operating system, choose the version that you download after clicking on the "windows" or "linux" button. Download the file to your desktop.
2. run the file
Run the downloaded file that you saved on your desktop.
3. connect the iOS device
Connect your iOS device to the computer and then turn it off.
4. "prepare to jailbreak (DFU)" button
Now prepare to perform DFU mode, then click on "prepare to jailbreak (DFU)" button
5. DFU mode
Use the instructions shown in the greenpois0n application to get into DFU mode.
6. start the jailbreak
After you get into DFU mode, click the "ready to jailbreak" button. The process will then start, which will take a few minutes.
7 jailbreak done
After a while the jailbreak will be done and you click the "quit" button.
8. Restart your device and install Cydia
Your device will reboot. After rebooting, you will have a new "loader" icon on your desktop. Run her. On the boot screen, choose to install Cydia if you want. After successfully installing Cydia, you will be asked if you want to remove the loader. Then click on the home button and your device will reboot.
9. done
All is done. You can start using jailbreak.
I hope you find the guide useful.

Libor Kubín: a very intelligent opinion. Of course we took a picture of you... thank you
Will there be any JB for iPhone 3G?? Or maybe it already is and I missed something??
redwsn3w probably works on ip0g if I'm not mistaken. Anyway, the pwnage tool should be released by the end of the week, but I don't know if it will support 3g...
And my cat is still nothing...well, I'll wait.
I'm still waiting too, I have to be patient for a while :).
Hello,,
could anyone advise how to start tethering for O2? Preferably via bluetooth and without the need to use an external program such as MyWi or cosiPAD? Thanks a lot for the advice. I don't go to the bureaucratic forum forum.iphone.cz.
Well, as far as I know, o2 is the only operator in the Czech Republic that does not provide tethering. the only option is to jailbreak.
I only need JB for tethering with O2, otherwise I have bought all the apps and I don't intend to change anything. O2 is really… pissing me off with this one.
For God's sake, are these people sane? Sure, I appreciate their efforts, but for god's sake OS X support is nowhere to be found??
OS X nowhere? ……what about Parallels or VMware? ;-) ……..this is how we had to suffer when everything was published only for MAC :-) ………that's disgusting huh? :D
JB Limera1n from GeoHot is already available for mac
http://limera1n.com/
Great, thanks for the info :).
Well, I don't make it worse like that. I, unlike some mac users, remember what I started with :)))). But I wouldn't do it through Parallels, I read somewhere that it doesn't do any good.
My iPad turned off while uploading the jailbreak and can't turn it back on. On the PC, it showed that a device was connected and information about the DFM mod, and with that it goes out. Here I have a black iPad that cannot be turned on. I am asking for advice on how to proceed.
Try DFU mode and reinstall the firmware on the iPad. I don't see any other solution.
Good day everyone,
I have a question, can JB help me to get xls doc pdf and other files to my iPad. The iPad is great, but I would also like to use it for work and so I need to view a lot of word files, xls files and pdf files. I want to show customers photos of our products, etc. on it. Photos are not a problem, but what about the rest? Is it possible to somehow get it on the iPad? Other than email? And how and where to store it?
Thank you very much for the advice. If it doesn't work, I'll have to say goodbye to the ipad and buy a new macbook air instead. It would be a shame, because I really enjoy using my fingers on the iPad screen.

JB is completely useless to you in my opinion, I don't see any use for him. You don't care about storing files, there is no such thing as a (visible) directory structure on the iPad. You get the files there and sync them via iTunes.
You can view and edit xls files using Numbers, doc and xls Documents To Go. You can view the PDF using a PDF reader. Attention, these are paid applications, you can find cheaper ones. There is at least one alternative to each program.
I wanted to ask if this JB also works on the iPhone 3G and if anyone has tried it? I recently switched to OS 4.0.1 and I don't know which JB to use,
Thanks a lot for the advice.
Could someone here (for us apple newbies) comprehensively review the difference between JB limerain and greenpoison? Plus, an article on how to deal with it (especially in iTunes) and what to do when 4.2 (or any new version) comes out would be nice. Thanks a lot.
Thanks for the tip. Anyway, the only difference between the mentioned jailbreaks is that limerain was released by Geohot and Greenposion Chronic dev team. Otherwise, they use the same security hole, so I don't see a real difference between them. As for iTunes, when a new version of iOS comes out and you update your device with it, you lose your JB and have to wait until hackers find a new security hole and release a new JB for the new iOS version. So if you have JB, I advise you not to immediately upgrade to a higher version of iOS after it comes out ;). If you have any further questions, you can contact me at petr@14205.w5.wedos.net or to our forum.
I would need advice on what to install so that it works for me Operators here I have an iPhone 4 os 4,1 from America and I tried both tools, the phone is activated, itunes does not reject it with a Czech card, but the sim does not work. Thank you
hi, thanks for the instructions on JB, I think it works well =) but could you advise me what to do next? I finished everything according to the instructions and on my iPod (4g) only "cydia" crashed and otherwise I have the impression that nothing has changed... could someone please advise me what to do next so that I can insert applications, games and the like?
Cau, please, I installed JB on my ipod touch 4g os 4.2.1. (greenPois0n) but when I put the downloaded game in the itunes library and then sync, the app installs and then it throws an error saying it can't be installed etc... pls any advice? how do i get the games??? PLEASE, GIVE ME AN ADVICE! Thanks for the anwers.
