How to Unlock iPhone 2G with OS 3.1.3

If you are using iPhone 2G then there’s good news for you! The latest operating system 3.1.3 can be jailbroken as well as unlocked on iPhone 2G. It’s because the baseband doesn’t get updated when you update the firmware. I just unlocked mine yesterday. Well, here’s a short tutorial to unlock an iPhone 2G:

Files required:
iPhone 3.1.2 firmware
iPhone 3.1.3 firmware
Bootloader Files – bl39.bin & bl46.bin.
Redsn0w 0.9.4

How to Unlock iPhone 2G with OS 3.1.3

Firstly, update your iPhone’s firmware to 3.1.3 using iTunes.

Create a folder on desktop and name it as ‘RedsnOw’. Download iPhone 3.1.2, 3.1.3 firmwares and redsn0w. Also, download Bootloader Files – bl39.bin & bl46.bin. Save all the downloaded files in this folder.

Now, connect your iPhone using the USB cable.

Start RedsnOw, browse the 3.1.2 .ipsw firmware file from the folder and click on ‘Next’ to proceed.

If you want to unlock the iPhone then select ‘Unlock’ option from the window. Make sure you also select ‘Install Cydia’. Once done, click on ‘Next’ to continue.

A bootloader window will appear, perform the instructions given on the screen.

Once you finish with the above process switch off the device and click ‘Next’ to start with DFU mode. Put your phone in DFU mode by using screen instructions. (Hold the power and home button simultaneously and connect the cable. You need to hold them for 10 seconds and then release the power button while holding the home button. Hold until the phone enters into DFU mode.)

The redsnOw tool will automatically start the unlocking procedure. Just wait for few minutes to get your iPhone unlocked.

    Hi Josh,

    Do you mean to say that your phone already has 3.1.3 firmware and you’re interested in jailbreaking, unlocking it?

    My phone has 3.1.3 firmware, but the redsn0w does not recognize the firmware 3.1.2… I used to have firmware 2.1.2 and my phone was unlocked, i updated my phone to 3.1.3 and then tried to jailbreak my phone… then the Itunes told me to restore it… i thought that it was a procedure to jailbreak it… so i restored it and now i’m having problems unlocking it… any advice?

    I pick-up an iphone 2g. Suppose to be unlocked and jailbroken. It does have cydia already. But I can’t log onto the internet. It keep saying there’s no data plan. I’m with AT&T and/was using a Blackberry 8900. What do I need to do?

    AMAZING! I have spent the last 6 hours following tutorial after tutorial, each time downloading files from their specific links and it was no until I hit your tutorial that it all finally worked! Thank you so much. Even though this was a very short tut the links all worked and the process resulted in an updated unlocked and jailbroken iphone 2g. Thanks :)

    This is an AMAZING GUIDE. THANK YOU. Guys don’t forget to download a bootloader 3.9 and 4.5 to the same destination folder as your IPSW and rensn0w.
    Cheers

    If you are having trouble “finding” the 3.1.2 ipsw with redsn0w, it is because when you downloaded it, your system defaulted it to a WinZip or a WinRAR. After you click to download the file and you select the save point, there is a dropdown below the path/filename that will allow you to change the type of file.
