  • [Windows] How to Jailbreak and Unlock iPhone 2G Firmware 3.0 with RedSn0w
    This guide will teach you how to jailbreak AND unlock your iPhone 2G running 3.0 firmware using RedSn0w on Windows.

    I strongly recommend you backup and restore your iPhone 2G 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 2G 3.0 firmware file available for download here. You also need the 3.9 and 4.6 bootloader files. Download 3.9 here and 4.6 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.



    Find your iPhone 2G 3.0 firmware file you downloaded earlier. Select it and click Open.



    RedSn0w tells you that the ISPW is successfully identified. Click Next.



    There will be a quick pop up.



    Select your options to Install Cydia and Unlock. If you don't need to unlock your iPhone 2G you can de-secelct Unlock



    If you are unlocking you need to located the 3.9 and 4.6 bootloader .bin files you downloaded earlier.









    Now that you have told RedSn0w where the bootloader files are click Next.



    At this point you should make sure your iPhone 2G is plugged into your computer AND turned 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 and Unlcoked. Don't mess with your phone while all this is going on. After your phone restarts you are done!

      Only the 3G S has the compass app, as the iPhone 2G and 3G both don't have the right chip.

      And tethering can be enabled by going to help.BenM.at/help.php on your iPhone.

      Tethering is in Settings>General>Network.

      Check this on BigBoss
      4) Some apps are still not ported to 3.0. Most apps will work. But some things that require some hacking to work will probably not work. Known issues (there may be more):

      - Quickgold is replaced by spotlight, but spotlight wont launch hidden apps.
      - BiteSMS, MySMS, iRealSMS are not yet updated (BiteSMS and iRealSMS are due to be released anytime though and could be ready by the time jailbreak comes).
      - Backgrounder - No development for 3.0 has started on this great app

      You will have to use the firmware with itunes first to restore to 3.0 and then use redsn0w to activate and jailbreak
