How to Jailbreak Your iPhone 3G iOS 4.1 with RedSn0w

By , Sep 21, 2010

This step by step guide and tutorial will show you how to use RedSn0w 0.9.6 Beta 1 to jailbreak your iPhone 3G iOS 4.1. So far, this only works for the iPhone 3G and the iPod Touch 2G, and is a Mac only tool (although a Windows version is coming).

Before we start the tutorial, make sure you read and understand this. Once you have read this article through, come back here and let’s work on jailbreaking your iPhone 3G iOS 4.1 with RedSn0w…

How to Jailbreak iPhone 3G iOS 4.1

Step 1: Make sure you are running the latest version of iTunes (iTunes 10).

Step 2: Download iOS 4.1 for iPhone 3G to your desktop from our iPhone downloads section.

Step 3: Update your iPhone to iOS 4.1 via iTunes.

Step 4: Download the latest version of RedSn0w from here.

Step 5: Point RedSn0w to the iOS 4.1 you downloaded in step 2.

Step 6: Select “Install Cydia”.

Step 7: Follow the onscreen instructions.

Step 8: Let RedSn0w do the hard work for you. Once jailbroken, your iPhone will reboot.

That’s all there is to it. You will not be able to unlock, at least for the time being. For the most up to date information about jailbreaking, check out this page, and look at this for up to date information about unlocking.

    Redsn0w 0.9.6 b1 seems to be really buggy and slow on 4.1. I had to restore it back to normal in order for it to run properly.

  • Bridges7658

    When will there be a unlock for IPhone 3G 4.1?

  • Samantha

    This may be a stupid question, but how do I Step 5: Point RedSn0w to the iOS 4.1?

  • Adrian

    deezo. lol. it is bcoz of redsnow? i thought my iphone 3G not suits with iOS4.1. coz my ip now damn slow n laggy. =.=

  • deezo

    Adrian, it’s definitely redsnow. Restore it back to stock and the phone flies.

  • deezo

    Samantha, you have to point it to the 4.1 IPSW you downloaded to your desktop.

  • Adrian

    owh. but how i supposed to do that? im really noob in this. ive’d tried to restore to ios4.0 but error. since i don have shsh blobs for 4.0. izzit true that if i don have shsh blob, i cant downgrade my iOS?

  • deezo

    Adrian, the erroring is baseband 5.14.02 preventing you from downgrading. I upgraded because I got tired of the slow speed of my apps and didn’t read the Iphone Dev blogs before i did it. So I’m stuck at this point until they make an unlock for this baseband. Yes, my phone is faster on 4.1 but Apple is full of idiots trying to prevent Jailbreaking as if they still own the phones or something. My phone isn’t even under contract so they should just unlock it and cut the crap.

  • Adrian

    owh. so what is ur suggestion for me? wait for unlock then downgrade my iphone or stay with iOS4.1 n wait for stable redsnow?

  • Sean

    The rednow link ■RedSn0w 0.9.6 beta 1 will not work. It directs me to and website that says oops this link appears to be broken. What do i do

  • Adrian

  • deezo

    Wait for the unlock Adrian. I’m in the same boat and I want to smack myself. My phone is boring now and I’m paying too much per month thru AT&T.

    redsn0w_win_0.9.6b2 gets stuck in the ‘Uploading RAMDisk’ step

    It took me quite some time to crack this but the best way to solve this (BTW, I’m running Windows 7) is to right click on the executable and enable compatibility mode (set mine to WinXP SP3). Once this is done, right click again on the executable and run as an administrator. This should do the trick.

  • deezomaxima

    Yes, I had to do the same on Win7. I like this version of Redsnow. Much more stable and smooth running that B1.

  • kc

    Thanks deezomaxima. That worked like a charm for me. You rock man! Thanks a bunch….

    • kc

      Sorry, I meant to say Thanks Jose! :P It’s been a long week for me.

    Hi i need help when I download my 4.1 IPSW firmware and unzip it creates a folder containing 6 items, non labled IPSW. When I Browse with Redsn0w to this folder to jailbreak my 3G it will not show any IPSW all it shows is another folder called Firmware which contains empty folders.
    Am I doing something wrong as Iv’e tried Redsn0w, Sn0wbreeze and various IPSW’s.
    Totally stuck and lost to what to do, do I need to convert them???

  • andrei

    what am i doing wrong?
    did everything above and i get the same thing every time.
    stops at “waiting for reboot”, tried to run as admin in win7, in compatibility with xp sp 3, sp2, tried to run in win xp sp3, nothing works.
    in win7 before it saying “waiting for reboot” it tells me that “the device will run faster if i connect it in to a usb2.0″ but it is connected in to a usb2.0.
    thanks in advance for your support!
