Finally, there’s is a new addition to the iPhone jailbreak tools lineup as the Sn0wBreeze from the house of iH8Sn0w is out now.

Sn0wBreeze is another jailbreak tool for iPhone and iPod Touch 3.1.2. It does the same thing PwnageTool from the Dev-Team does but unlike PwnageTool, Sn0wBreeze is fully compatible with Windows OS (7, Vista, XP). If for any reason you could not get the previous iPhone jailbreak tools (BlackRa1n, PwnageTool, RedSn0w) to work for you to jailbreak iPhone OS 3.1.2, Sn0wBreeze is there to give a shot. Create the Custom IPSW file with Sn0wBreeze and jailbreak iPhone 3.1.2.

In this guide you’ll learn, how to jailbreak iPhone OS 3.1.2 with Sn0wBreeze by creating a custom firmware.

NOTE: Sn0wBreeze is still in beta. So, BlackRa1n and PwnageTool are still recommended tools to jailbreak iPhone and iPod Touch. Follow the links below if you want to use BlacRa1n, PwnageTool or RedSn0w to jailbreak iPhone. If you want to go for Sn0wBreeze Jailbreak, continue reading.

PREREQUISITES

Download iTunes 9.0.2
Download iPhone OS 3.1.2 firmware for your iDevice

How to Jailbreak iPhone 3.1.2 with Sn0wBreeze

Step 1
Make sure you’ve installed the latest version of iTunes. Open the iTunes and backup your iPhone data.

Step 2
Run the Sn0wBreeze and hit next button.

Step 3
choose Simple Mode. We cannot get Expert Mode work properly because it’s still in beta. So only Simple Mode is available.
Click the Next Arrow button.

Step 4
Sn0wBreeze will ask for the IPSW file for your iDevice. Click on the Browse button and navigate to the folder where you put your iPhone OS 3.1.2 IPSW file and choose the downloaded firmware 3.1.2.

Sn0wBreeze will verify your selected firmware 3.1.2 file.
Hit Next.

Step 5
On the next screen, Sn0wBreeze will ask you: Do you want to activate your iPhone?

Hit Yes button for hacktivation (for unofficial carriers)
Hit No if you want to use official carrier (AT&T etc).

Step 6
Hit the Start button. SnowBreeze will start building custom firmware for your iPhone that we will use later to jailbreak iPhone OS 3.1.2.

Step 7
Once the custom IPSW file building process is complete, now it’s time to restore your iPhone with that custom firmware that you just built using Sn0wBreeze.

Connect your iPhone to iTunes and select your iPhone from the left navigation pane in iTunes. Hold Down the SHIFT key on your keyboard and hit the Restore button (SHIFT + Restore)

Step 8
Now the iTunes will ask for the IPSW firmware file.
Browse to the custom firmware that you built using Sn0wBreeze and select it.

iTunes will Restore your iPhone with custom iPhone OS 3.1.2 created with Sn0wBreeze. Once the iTunes is done with the restore process, your iPhone will restart automatically.

Voila! you’ve a fully jailbroken iPhone with OS 3.1.2.

Support for the IPhone has been poor recently – blackra1n has caused reboot issues, issues with wireless and also with youtube and push notifications. Hopefully this may fix issues – or not?

I’m guessing that creating a custom bolt logo (I really want the silver pineapple from Pwnage Tool!!) isn’t available yet as it’s part of the “Expert” process?

Will this otherwise be ok for my 3GS (old bootrom), running OS 3.0.1 build 7A400 and modem firmware 04.26.08? I’m on an offical carrier and don’t care about unlocking.

@GoranRi- the bootrom version is important when jailbreaking a 3GS- the older 3GS’s are open to the exploit used to jailbreak.. The phone can turn on/ restart without needing to be plugged into a computer. This is NOT the case with 3GS’s running the later bootrom (such as yours). These units can sti be jailbroken- BUT if it requires a restart or your battery drains and it turns off- the phone cannot restart by itself- it would need to be re-jailbroken before it will turn on again. This is being refered to as a “tethered jailbreak”.

It makes me glad I have one of the first 3GS’s!

Hope this info helps!

It didn’t worked for me. I have 3GS FW3.0, with old boot room, and was previously jailbroken with purplera1n.
I’ve tried this process for 3 times and on 3 different machines running Vista 32 Bit, Vista 64 Bit, and windows 7.
Every time I had same error messages “14″ while restoring with itunes.

Please Help.
