How to Jailbreak Your iPhone 3GS, iPhone 4 Using Greenpois0n (Windows)
These are instructions on how to jailbreak your iPhone 3GS and iPhone 4 using Greenpois0n for Windows. Greenpois0n supports the iOS 4.1 and iOS 4.2.1 firmware. Use Limera1n if you want to jailbreak iOS 4.0, iOS 4.0.1, iOS 4.0.2.

Remember: Do not update to iOS 4.2.1 if you need the unlock. Ultrasn0w does not support
that baseband yet. The only exception is the iPhone 4. You can
update to iOS 4.2.1 without upgrading your baseband by following this tutorial.

Step One
Open your web browser of choice and navigate to http://www.greenpois0n.com. Click the Windows link at the bottom of the screen.

Step Two
When prompted save the download to your desktop

Step Three
Double click the downloaded gp_win_rc5_b2.zip file then drag the greenpois0n.exe file to the desktop. Double greenpois0n.exe from the desktop to launch the application

Step Four
Power off your iPhone then click the large Prepare to Jailbreak (DFU) button

Step Five
You will now be instructed on how to place your iPhone into DFU mode. You can get help with this here.

You will be asked to press and hold the sleep button for 2 seconds.

Continue holding sleep; press and hold home for 10 seconds.

Release sleep button; continue holding home for 15 seconds.

Step Six
Once your iPhone is successfully in DFU mode you may click the Jailbreak button.
