Step One
Create a folder on your desktop called Pwnage

Download RedSn0wfrom here and place it in the Pwnage folder. Likewise, download the latest 3.0 firmware from below and place it in the same folder.

3.0.0 (3GS): iPhone2,1_3.0_7A341_Restore.ipsw

Extract the RedSn0w executable from the zip file to the Pwnage folder.

Step Two
Connect your iPhone to the computer and launch iTunes.

Select your iPhone from the list of devices on the left. Now hold down shift and click the Restore button. Restore is preferred as it won't create any wasted space on your iPhone.

Navigate to the Pwnage folder on your desktop and select the firmware ipsw. Click the Open button to continue.

Step Three
Once iTunes has finished updating your iPhone to the desired firmware you may launch redsnw0w.exe from the Pwnage folder on your desktop.

Step Four
Once RedSn0w opens click the Browse button

Step Five
Select the firmware ipsw we placed in the Pwnage folder on our desktop then click Open

Step Six
Once the firmware has been verified click the Next button to continue.

Step Seven
Make sure Cydia is selected and click the Next button.

Step Eight
RedSn0w will now instruct you on how to put your iPhone into recovery mode. Disconnect you iPhone 3GS from the computer then 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.

Step Nine
Your iPhone will now reboot

Step Ten
RedSn0w will then begin uploading the new RAM Disk and kernel.

Step Eleven
Once this is complete you will be notified that RedSn0w is done. Click the Finish button. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.

I am not a Macintosh/Apple fan, I use Windows/Linux/Android. However, I bought an iPhone 3G 16GB for $50 from a friend. I've Jailbroken it but now I face two problems. Cydia tells me that there are some Essential Updates to download and install but when I confirm the installation none of the files download successfully. I get an error for each one then I'm taken back to the Cydia main page. Secondly, now that I'm Jailbroken, when I plug in my iPhone and open iTunes it asks me to Setup as New iPhone or Restore from Previous Backup, until I choose one of these options I can't sync my iPhone to my PC and/or copy music over etc. Why? How can I get by this? After these problems are resolved I need to unlock the iPhone but I can't move forward until the Cydia issues are fixed... Help!!! PAinguIN

Does this jailbreak method require a AT&T SIM card inserted in the phone? I\'m getting a locked iphone 3gs and need to unlock it. Thanks.

If you have gotten a 3gs within the past 3 months there is a new block and they cannot be unlocked. Not sure if this is your problem but figured I\'d let you know.
