  • [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!

      Then you will have to restore again. Sorry.

      Yeah, I'm doing that now. Hopefully it will work this time.

      Should I use redsn0w 0.7.1 just to be safe? It only has the Cydia option.

      On the screen that offered to install Cydia (checkmarked) it also offered Icy (not checkmarked). What does that application do?

      My iPhone seemed to process all the jailbreak steps as dictated in this forum. However when it rebooted, everything looks exactly the same *except* for the Cydia app on the springboard. Is this the expected result of jailbreaking? If so then what's the next step?

      Hey guys i just did a fresh apple restore then redsnow. Everything worked perfectly. The issue I am having is with sbetting toggle. I installed it, it says its there, but it wont open. I have hardly installed anything yet so i don't know what could be conflicting with it. Anyone know what the problem could be?

      thanks
      redsnow RULES! without it the iphone would be nothing more then a pretty paper weight.

      Don't install Icy, Cydia might not work. Icy sucks anyways.

      Yes it's supposed to look the same. The next step is whatever you want to do with your jailbroken iphone. Features, apps, themes, etc.. all in cydia.

      So a bit of a problem here. Whenever I try to jailbreak only installing Cydia, redsn0w crashes. If I try it installing Cydia and Icy, it works fine, except for the Cydia not updating issue. Anybody got any ideas?

      As that's where the Dev Team host their files, are you surprised?
      You can also download it from the download section here on MMI.

      I guess I'm just surprised that it's not on the redsn0w website... but then I'm sure if I were keeping up with this stuff I wouldn't be :P
