** If you would like to jailbreak on the 3.0.1 firmware you can follow these exact instructions; however, in Step Two restore using this 3.0.1 iPhone firmware file instead of the 3.0 one. Continue with the instructions as indicated.**
Create a new folder on your desktop and name it Pwnage
Download RedSn0w by clicking here and put it in the Pwnage folder that you just created. Also download the latest 3.0 firmware from the link below and put it in the same folder called Pwnage.
3.0.0 (3GS): iPhone2,1_3.0_7A341_Restore.ipsw
Extract RedSn0w from the zip file and save it on the Pwnage folder. Note: you must extract otherwise the jailbreak process won’t work.
Connect your iPhone to the computer and launch iTunes.
Select your iPhone from the list of devices on the left. Now hold down Option and click on Restore. Restore is preferred since it will not create any wasted space on your iPhone.
Navigate on the Pwnage folder that you created on your desktop and select the firmware ipsw. Click Open to continue.
*Note: If you are already on the 3.0 firmware and have not jailbroken then you may skip this step.
Once iTunes finishes updating your iPhone to the desired firmware, you may launch redsnw0w.app from the Pwnage folder that you created at the desktop.
Once RedSn0w opens click on Browse
Select the firmware ipsw that you placed in the Pwnage folder and click Open
Once the firmware has been verified click Next to continue.
Make sure Cydia is selected and click Next.
RedSn0w will now instruct you on how to put your iPhone into recovery mode. Disconnect your iPhone 3GS from the computer and power it off. Then hold down the Home button while reconnecting the device to the computer. Don’t let go of the button until RedSn0w detects the iPhone and begins installation.
Your iPhone will now reboot
RedSn0w will now begin uploading the new RAM Disk and kernel.
Once the uploads have been completed you will be notified that RedSn0w is done. Click Finish. When your iPhone finishes rebooting (it may take a few minutes) it will be jailbroken with Cydia on the SpringBoard.
