Just a few moments ago, P0sixninja released the GreenPois0n untethered jailbreak for windows! I know this is going to be very exciting for a lot of you, so I will try to make this introduction short and sweet. First off if you have not been paying attention to when GreenPois0n was released for the Mac OS X operating system, it is important to note that this untethered jailbreak does not require the iOS 4.2b3 SHSH blobs (which are developer only SHSH blobs). Also this jailbreak does not contain any major bugs/errors that early versions of the redsn0w beta untethered jailbreaks contained.
Since the release of the GreenPois0n untethered jailbreak for Mac OSX we now know that:
- You can run GreenPois0n over a currently tethered iOS 4.2.1 jailbreak to untether your iDevice
- This version of GreenPois0n does not hacktivate or preserve your iPhones baseband
Keeping the above points in mind, we are going to move ahead and start the tutorial.
Note: If you followed our last tutorial on using GreenPois0n RC5 you will notice that the steps are almost identical.
Step 1) – The first thing you are going to need to do is ensure your iDevice is running the iOS 4.2.1 firmware. This is the only firmware version that GreenPois0n RC5 supports.
Step 2) – Once you are running a clean install of the iOS 4.2.1 firmware, you are going to have to download GreenPois0n RC5 for Windows (Want the tutorial for Mac OS X? Click here). You can do this by clicking our download link below.

Step 3) – Once you have downloaded GreenPois0n RC5 for windows, you are going to need to extract GreenPois0n to your desktop. You can do this by right click on the gp_win_rc5_b2.zip file and clicking the extract button.
Once GreenPois0n has been extracted to your desktop you are going to need to double click the greenPois0n.exe file.
When GreenPois0n is up and running you will now need to plug your iDevice into your computer via USB. Once your iDevice is successfully plugged into your computer, you can begin the jailbreaking process by clicking the jailbreak button (however make sure you are anticipating what comes next).
Once you click the jailbreak button you will then need to put your iDevice into DFU mode. GreenPois0n provides on-board instructions for putting your iDevice into DFU mode. Please follow the instructions exactly to avoid errors with your jailbreak.
Note: In case this is your first time jailbreaking, here is what to expect when putting your iDevice into DFU mode:
- Get ready to start (5 seconds)
- Press and hold the sleep button (3 seconds)
- Continue holding sleep; press and hold home (10 seconds)
- Release sleep button; continue holding home (10 seconds)
Step 4) – Once your iDevice has successfully entered DFU mode, GreenPois0n will begin jailbreaking your iDevice. Now you just need to sit back and wait for GreenPois0n to respring your iDevice into a jailbroken state.
When your iDevice does respring into a jailbroken state you will need to click the loader icon on your SpringBoard to install Cydia (the 3rd party installer)
When you click the loader icon, you simply need to click on the Cydia tab and the loader.app will begin installing Cydia to your iDevice. Once Cydia has been successfully installed, you can delete the loader.app. Note: If Cydia is not displayed on your springboard after FIRST clicking the cydia tab through the loader.app, you may need to simply restart your iDevice.
As you can see the process for jailbreaking untethered on the iOS 4.2.1 firmware is very simple! Let us know if you need any help, and we will gladly help you as best as we can.
