  • [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!

      Update to 3.01 then use 3.0ipsw to RedSn0w. No need to do it twice.

      hi

      I am also using iphone in Tanzania with Vodacom.

      Just wondering if you (or anyone) knows how to install the manual settings onto the iphone to enable internet tethering to work? It is available with Blackberries so I don't know why it should not work in principle with iphones.

      N.

      woohoo confucious is rocking this thread

      Uhh.. Not sure about tethering because I've never used it (tethering with T-mobile's EDGE? ha!) but you can put in your APN settings at Settings>General>Network>Cellular Data Network.

      I tried to update to 3.01 using redsnow 0.7.1 and it will not verify the IPSW (Unable to recognize specified IPSW). I have tried redsnow 0.7.2 and .8 both will just not work at all the program errors out. I have used 0.7.1 in the past no problem. Does anyone have any ideas why 3.01 will not work? I have downloaded it twice to make sure it is not the IPSW.

      Upgrade to 3.0.1 through iTunes then run Redsn0w and when it asks for the ipsw give it 3.0

      It would still be 3.01? I thought it would downgrade to 3.0 then. I am in the process of JB it right now. thanks for the help angiepangie.

      Yes it'll still be 3.0.1.
      Redsn0w doesn't change firmwares, and it doesn't work anywhere near the SMS patch
