This guide will show you how to jailbreak your iDevice using the new greenpois0n software by the Chronic Dev Team. It works on iPhone 3GS, iPod Touch 3G, iPad, iPhone 4, iPod Touch 4G 4.0-4.1 and beyond+++. It only works in Windows at the moment, although a Mac version of the software should be out soon.

Download the greenpois0n software from here. It is Windows only at the moment. Make sure your device is plugged in to the computer and powered OFF. Double click the greenpois0n icon to run it, press “Prepare to Jailbreak (DFU),” and follow the instructions to put your device in DFU mode. NOTE: The “sleep” button is the top power button, the home button is the button on the face of the device.
When it’s finished putting you in DFU mode, you can let go of the home button, and press “Jailbreak!” in the bottom left of the greenpois0n program.
The iDevice will flash a white screen a couple times, and evenautally also start up in recovery mode – just let it sit. The entire process takes a couple minutes, during which greenpois0n will simply say “Jailbreaking…”
When it’ finished, it will tell you “Jailbreak Complete!” in the bottom left of the window, and you can press quit. That’s it! You’re jailbroken! Wait for the device to power on, and enjoy your newly jailbroken device.
NOTE: At the moment there seems to be a bug where greenpois0n is not actually running the ramdisk on some systems, this should be worked out soon. That’s not a harmful bug – it just means while the program will think you’re jailbroken, you won’t be.
