These are instructions on how to unlock and jailbreak your iPhone 2G on the 3.1.2 iPhone firmware using RedSn0w for Mac.

The Windows version of this tutorial is here. If you have an iPhone 3GS please follow these instructions. If you have an iPhone 3G please follow this tutorial.

Step One
Create a folder called Pwnage on your desktop.

Download the following files and place them in the Pwnage folder you just created:
- RedSn0w
- BL 3.9
- BL 4.6
- 3.1.3 (2G): iPhone1,1_3.1.3_7E18_Restore.ipsw

Double click the redsn0w zip to extract the redsn0w folder to the Pwnage directory.

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 Option 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 open the Pwnage folder on your desktop and launch the redsn0w application from the redsn0w folder we extracted earlier.

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
From this window you can select the jailbreak options you would like. If you have already pwned your device check the Already pwned option.

Verbose boot displays detailed information on boot of your device and is generally only needed by developers and advanced users.

Make sure the Cydia and Unlock options are selected. For this tutorial we will also select Custom boot logo and Custom recovery logo.

When you click to select each custom logo option a dialog window will appear asking you to select the image. Locate the image you would like to use then press the Open button.

*Remember the rules for boot logos are: RGB or Grayscale format with Alpha channel and dimension below 320x480. If you would like to use the iClarified ones they can be found here: Boot Logo, Recovery Logo

Click the Next button to continue

Step Eight
We will now need to set the location of our bootloader files.

Click Browse and select the 3.9 bootloader file from the Pwnage folder on your desktop.

Click Browse and select the 4.6 bootloader file from the Pwnage folder on your desktop.

Click the Next button to continue.

Step Nine
Please plug your iPhone into the computer and make sure its OFF then click the Next button

Step Ten
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Eleven
Your iPhone will now reboot

Step Twelve
RedSn0w will then begin uploading the new RAM Disk and Kernel.

Step Thirteen
Once this is complete you will be notified that RedSn0w is done. Click the Finish button.

When your iPhone finishes reboot (5 minutes or so). It will run BootNeuter then be unlocked and jailbroken with Cydia on the SpringBoard.

*As usual a big thanks to the iPhone Dev-Team for their hard work and contribution to the iPhone community.

The tutorial and the links iClarified giving here are NOT MACTHING! I am now stuck with a locked iPhone. Upgraded to 3.1.3 from the given link but stuck on step 4. Its \'Unrecognized IPSW\' with Redsnow 0.9.4. D*mn iClarified!

Hey Alex, I ran into the same issue on step 4. So what I did is download the iPhone1,1_3.1.2_7D11_Restore.ipsw file and used that instead and it worked. You can get it from the link below. After I used that file I continued following the steps and it worked fine. Hope it works for you too.
