  • [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!

      Not sure what you guys are doing wrong, follow the guides to a t is all I can say, Im jailbroken fine youtube works flawlessly, my ipod icon is there lol, the amount of space shown for my device is correct

      only thing i havent tested is ssh although if it doesnt work im certain its just a 3.0 compatibilty issue and a new working ssh will be on cydia shortly

      I just finished downloading and install Redsnow and it works just fine, the only thing i am having issues with is that when i try to open the internet it tells me that: Could not activate cellular data network: You are not subscribed to a celluar data serve. Which I am and it was working just fine before, any idea what I can do.

      put your APN settings in. Data network EPC.tmobile.com, or wap.voicestream.com or internet2.voicestream.com.

      All depends on your cell company. but its your network apn settings. bla

      My phone has this screen for over 5 minutes:

      "Downloading Jailbreak Data..."
      and right below an endless spinning wheel.


      Spinning wheel of death?
      Please help...


      EDIT: The phone got out of that screen by itself but now I have that screen with the iTunes icon and the usb cord... DAMN!

      I tired searching APN, some how it does not show up under network. The only thing that shows up Settings>General>Network> Data Roaming or VPN or Wi-FI. I have att and I am currently paying for a data plan.

      no A2DP in iphone 2G 3.0.....
      so disappointing...I m sure that iphone 2G chip also supports A2DP like 3G and 3GS.
      I hope we get a jailbreak solution for this!!!

      Can somebody post about how long it took to do? It seems like it's just stuck on the very first 'waiting to reboot' screen.

      EDIT: I finally got it to work. I used the IPSW that was created on my machine, and it went fast. 10-15 seconds.

      I can't get this to work. During the jailbreak, I get a error message that says redsn0w has stopped working.
