Good news! Sn0wBreeze 1.6.1 has been released! iH8sn0w, the developer behind Sn0wbreeze jailbreaking tool has just released the updated version which supports jailbreaking iPhone 3G/3GS-old boot/iPod Touch 2G and iOS 4.0 on Windows. Sn0wbreeze 1.6 is nothing but the PwnageTool port to Windows and hence it can create custom firmware for iOS 4.0 while preserving baseband to keep your iPhone unlocked, unlike redsn0w.

PwnageTool 4.01 was released yesterday by the iPhone dev team to jailbreak iOS 4.0 on iPhone 3GS. But PwnageTool is only for Mac. For Windows users, RedSn0w 0.9.5 beta 5 was the only jailbreaking tool available which doesn’t work for iPhone 3GS.

If you have iPhone 3GS with old bootrom and already pwned on 3.1.2 with anything other than Spirit, then download Sn0wbreeze 1.6.1 for Windows and get it jailbroken now.

Guide to Jailbreak iOS 4.0 on iPhone 3G/3GS and iPod Touch 2G using Sn0wbreeze 1.6.1

As I already mentioned, Sn0wbreeze is just a windows port of PwnageTool 4.01. Hence only following devices are supported
iPhone 3G/3GS (old bootrom/already jailbroken with anything other than Spirit)
iPod Touch 2G (non MC model)

Here is a step-by-step guide for your reference

1. Start iTunes and backup your iPhone/iPod touch data

2. Download Sn0wbreeze and the original iOS 4 firmware file for your version of iPhone or iPod touch. Move all these files to your desktop.

3. Start Sn0wbreeze and select “Simple Mode”.

4. Select the correct iOS firmware ipsw file by clicking the “Browse” button.

5. Click on “Yes” when Sn0wbreeze asks you “Do you want to activate your iPhone?” for hacktivation. Click on “No” only if you are on an officially supported carrier like AT&T.

6. Sn0wbreeze will now create the custom .ipsw file for your iPhone which will be jailbroken.

7. Restore your iPhone to this custom firmware you just created. Click on your phone from the sidebar in iTunes and then press and hold left “Shift” button on the keyboard and then click on “Restore” button in the iTunes and then release the “Shift” button. Select the location of your custom .ipsw firmware and click on “open“.

8. iTunes will do the rest for you. Just wait while iTunes installs the new iOS 4 on your iPhone. iPhone will restart automatically and you should now have a fully jailbroken iPhone running on iOS 4.

  1. Hello,

    I have followed the all step upto 7,

    now my iphone is been restarted with new IPSW file, but,,
    there is no Cydia in my iphone, so basically its not been jailbroken,

    can you please email me, why this happens?

    My iphone details are as below

    iphone 3gs 16GB
    version: 4.0(8A293)
    Model: MC131B

    can you please help, how can I jaibroke my iphone ?

    thank you

  2. I have the same problem with the new ipsw. no cydia. in fact, the phone says only to insert sim card and then rejects my sim from another carrier. i can’t get beyond plugging into itunes and the sim card install. i can’t get into the phone at all to go to settings, etc. help

  3. hi there…
    i jail breaked my iphone3gs which was on 3.1.2 with spirit then i tried to jail break it with black rain and my iphone got stuck on boot logo …….so i was in trouble nothing worked at all. so i tried this snow breeze and upgraded my firmware as it was already jail broken by two tools … snow breeze created a firmware which was already jail broken now i have ois4.0 with jail break and from cydia i unlocked it as well from repo666 . 🙂 i am not sure if it works when you dont already have cydia in your phone.

  4. sn0wbreeze hasn’t worked on my phone. Every time i get an error 1600 or a 3194 without dfu mode. please help

  5. error code 1604 I got and clicked on the more info button and apple describes it to be an issue with the usb port if i remember correctly so I plugged the phone into a different port and tried again and no more error… however once all done… no cydia, pretty sure I used the newly created file as they were in two totally different folder.

  6. its a usb problem according to apple, I got it too. plug phone into different port and try again. if still, try on different computer or click the more info which brings you to the apple site and it lists other solutions for various error codes including this one.

  7. if this cannot jailbreak iphone 3gs OS 4.0. why they mentioned so anyway?
    they shouldn’t mention about jailbreaking iphone 3gs OS 4.0 if there’s no any program that can’t jailbreak yet.

    and is there anyone can tell me when will the program which can jailbreak iphone 3gs OS 4 will be released?
    i am dying to jailbreak mine!!!!!!!!!!!

    Thanks in advance,

    • why its mentioned? cos it can jailbreak iPhone 3GS. All models of iPhone 3GS –> NO. Read the post clearly “If you have iPhone 3GS with old bootrom and already pwned on 3.1.2 with anything other than Spirit” I can’t have all these as part of title, can I?
