  • [Windows] How to Jailbreak iPhone 3G Firmware 3.0 with RedSn0w
    This guide will teach you how to Jailbreak your iPhone 3G running 3.0 firmware using RedSn0w on Windows. You can unlock your iPhone 3G AFTER following this guide by using UltraSn0w. Directions on that are here. Anyways, lets continue.

    I strongly recommend you backup and restore your iPhone 3G to 3.0 firmware via iTunes BEFORE you begin this guide. By strongly recommend I mean restore to 3.0 firmware.

    You will need RedSn0w 0.7.2 which you can download here along with the iPhone 3G 3.0 firmware file available for download here.

    Once you have downloaded everything, extract redsn0w-win_0.7.2.zip to a location on your computer. You should see redsn0w.exe. Run it.

    Click Browse.



    Browse to where ever you downloaded your iPhone 3G 3.0 firmware .ispw, select it, and click Open.



    RedSn0w tells you that the ISPW has been successfully identified. Click next.



    You'll see a little window that says patching kernal for a second.



    Select Install Cydia and click Next.



    Plug in your iPhone 3G and turn it off. Once it is off click Next.



    RedSn0w gives you instructions. We are entering DFU mode now. First hold the power button for 3 seconds.



    Keep holding the power button and start holding the home button for 10 seconds.



    Release the power button but continue holding the home button for 30 seconds.



    RedSn0w does its thing. Let it.









    Finally RedSn0w has finished loading everything onto your phone. You will see a pretty screen on your phone as it is being Jailbroken. Don't mess with your phone will all this is going on. After your phone restarts you are done!

      I just unlocked and jailbroke my iphone 3g last night with firmware 3.0. What weird is that I can't sync in all my applications, only a few of them. It pops up a window that said it has some error codes or something. Can someone help me please?

      ok, this might be old news but i cant seem to jailbreak my phone. redsnow keeps crashing when its already in the process of "jailbreaking". what do i do? i used my windows and mac and both keep crashing. i avoided to check icy and only checking the cydia but it keeps crashing no matter what.

      can you give me the links if its not to much to ask? thanks oh btw can i unlock the iphone by this method?

      First place I'd look is under the pwnage section of MMI under JB and unlocking.

      Pwnage unlocks but preserves the BB so UltraSn0w can still be used.

      You needed to upgrade to FW 3.0 first in order to update your BB to 04.26.08
      Now you will need to shift restore your FW to standard 3.0 to upgrade your BB (make sure you do not use 2.1x)then restore your custom FW which will leave your BB at 04.26.08 but upgrade your FW to unlocked 3.12 then UltraSn0w will work.
