  • [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!

      Do not upgrade. do a clean restore. Upgrading will cause problems.

      Why not just use the one you get when you restore in iTunes? If you must download from anywhere else, just rename the .zip to .ipsw and it should work.

      On a 3G you need to run UltraSn0w to unlock.

      But he has AT&T so do I still need to unlock with ultrasnow or do I do that only when you need to use it with a carrier other than AT&T

      No. But you need to activate in iTunes first and leave the SIM in when you RedSn0w.

      I apologise, I saw you were on T and assumed he was too. I should have asked.

      Oh I will try it again tommorow then. How exactly do I activate the sim in iTunes though. Thanks!

      Just connect the phone to iTunes with the SIM in, it will tell you it is activating and if you wait it will just do it (you need an internet connection, obviously).

      Just tried it again today, worked perfectly. Thanks man!

      just one problem. i installed both icy and cydia. but now when i try to do anything in cydia like an essential upgrade it gives me an error.

      internal error, could not perform immediate configuration on essential

      and when i try to download anything else it gives me a similar error. i read on an ipodtouch forum that people are having similar issues but when they re jailbroke it and installed cydia only it worked fine.

      is there any other way to fix this without re jailbreaking it?

      i used resn0w 0.7.2 btw.

      You should redo it and NOT install Icy

      No, RedSn0w will be fine, just select Cydia and not Icy
