  • [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!

      The first time that I jailbrake with 3.0 the result was great...So WTH with 3.01? still the same computer with the same OS (Vista H.P) so...what could be the problem? then..Wait...I had a new antivirus...noooo waaay right? it can't be...and IT WAS..AVG for some reason crash with redsn0w. So I disable the AV and everything went smooth.

      Yup. A lot of people had to disable anti-virus to get redsn0w to run on Vista when it just came out.
      Strange though as I ran RS just fine on the one computer in our house running AVG

      Just restore in iTunes - that will load FW3.01 and download the 3.0 ipsw to use with RedSn0w.

      Thank you very much I was able to modify my iphone using redsnow ver 8.0 and IPSW ver 3.0. There is one problem after the modification still there is no connection with the phone network provider.

      RedSn0w doesn't unlock a 3G - it just jailbreaks. To Unlock you need to download UltraSn0w from Cydia.

      One question, will this process work for FW 3.01 or would i have to downgrade to 3.00 in order to Jailbreak my iPhone 3Gs 3.01 FW? Would the process to Jailbreaking FW 3.01 be the same as 3.00?

      ^It will work for 3.0.1. Yup exactly the same. Choose the 3.0 ipsw when redsn0w asks for it.

      ^ One more quick question before i go ahead and do this. Is the firmware on the first post the correct firmware to use if I wanted to jailbreak my 3gs 3.0.1 Iphone? It says 3g 3.0 firmware? Just double checking, if its not could you give me a link to a working firmware for the 3gs. Thanks in advance.

      Hi All,

      I just restore my 3G iphone through iTunes. As I got the phone from AT&T, but unfortunately I don't have AT&T sim card to activate it, what should I do the jailbreaking and unlocking without the sim card from AT&T?

      Thank you in advance for your help.

      So, Now I have a 3G iPhone without activation. Should I just do the jailbreaking with RedSn0w?
      Assume that I finish the jailbreaking well, could I enter the springboard without AT&T sim card? And without AT&T sim card, can I add the repo just through WiFi?

      Thank you so much in advance.
      I am so sorry for many question as I am really a newbie ...
