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.

How to Unlock/Jailbreak Your iPhone 2G on OS 3.1.3 Using RedSn0w (Mac)

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.

For those users that are planning to Jailbreak on OS 3.1.3, then I recommend adding this Cydia Source into Cydia after you jailbreak so you don't have to manually input all the Cydia Sources manually. This will automatically add all the best Cydia Sources and give you access to all the best Cydia Tweaks, Themes and Apps for FREE with just a push of a button. Follow the steps below. 1. Open Cydia 2. Tap Sources 3. Tap Edit 4. Tap Add 5. Type this url in the box (cydiasource,n e t) without the spaces and switch coma for a dot in the url. 6. Tap "Add Source" 7. Install the package labelled "All Sources". This will give you all the best Cydia Sources to have access to all the best Tweaks, Apps and Themes for FREE.

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. https://www.iclarified.com/entry/index.php?enid=750

Thanks a lot for the tutorials. I was able to unlock and upgrade my 2G phone. you guys rock!!!

I solved this problem. The link given in the download list at the top is: - 3.1.3 (2G): iPhone1,1_3.1.3_7E18_Restore.ipsw When you download this, it is "iPhone1,1_3.1.3_7E18" But, when you come to step 4, the current IPSW is not that version. Instead, it is: iphone1, 1_3.1.2_7D11_Restore.ipsw Google that, or download from here: http://mytopfiles.com/other/file/iPhone1,1_3-1-2_7D11_Restore/343202.htm Then in step 4, choose this file, not the first one you downloaded and used to back up your phone. The rest of the steps will work just fine.

Thanks for this info!

fernando_a - May 30, 2011 at 9:26am

Got it... Thanks!!! I did it on 2 different iPhone2G devices, and both are working perfectly. Just make sure you use the file "iphone1, 1_3.1.2_7D11_Restore.ipsw" as user "m" earlier pointed out. Good luck!

jones - July 2, 2010 at 10:56pm

It just doesn´t work! Redsn0w says "unable to recognize specified IPSW", I followed all instructions, had 3.1.2 and was trying to put 3.1.3 - the tutorial seems wrong, for my disapointment!..... didn´t do anything wrong.. any1?

Gigawatt - July 3, 2010 at 8:06am

Run redsn0w 0.9.4 and click on browse. Point it to the iPhone OS 3.1.2 firmware you just copied to your desktop. Make sure your iPhone or iPod Touch is already updated to OS 3.1.3

sky_finder - May 31, 2010 at 11:17am

Total confutation....what is the tutorial is going for... U put there to download 3.1.3 7E18 but U select 3.1.2 7D11 (also in windows tutorial) but U download is not the firmware. The other thing is not going for DFU mode. Is it down grade to 3.1.2 or just unlock. Pleas clear this.

hi, can i follow this procedure though I have a 2G still on 1.1.3 with 04.02.13:G? thanx for helping me out.

I apologize in advance if this is a repost, but I have not been able to find a solution to my "unique" problem. I purchased a USED iPhone 2G from a coworker and I was successfully able to jailbreak (blackrain) and unlock (bootneuter) the phone to use an AT&T gophone SIM card. The OS seems way slower (to be expected, I guess) than my 2nd Gen 32GB iPod Touch. I should say that I am a Sprint customer, using a Treo Pro and I only wanted to get the iPhone because of the camera, bluetooth, and built-in earphone and transmitter. I was using Vonage Mobile (free unlimited domestic calls in the US--I have actually tethered it to the Treo Pro and gotten decent call quality at times!) for the iTouch and discovered that in order to activate the iPhone version, there was a test call that needed to go through, hence the goPhone SIM and the unlocking process. Back to my problem. I have been unable to sync the device to iTunes and download my songs to the iPhone. It wants me to restore the phone and says that an iPhone (with my coworker's phone number) has already been synced to this computer. The reason I say my issue MAY be unique, is because most of the posters with unlocked iPhones seem to have "legit" AT&T iPhone accounts which is what I suspect may be my issue. My last resort, of course, is to restore the phone back to factory state, but I really don't want to lose my programs and such. I do have Pandora and Slacker, so I can listen to music most of the time, but I don't want to be restricted to wi-fi, since Edge is not really a practical option. ($20 for 100mb, and it is a pain to configure without a T-Mobile SIM card). So, again, what I really want is to sync my jailbroken, unlocked iPhone 2G to iTunes. Any suggestions?
