sn0wbreeze 1.5.1 is the Windows version of PwnageTool. If you don’t know what PwnageTool is, it lets you create your own custom IPSW firmware files to be used on iPhone’s and iPod Touch’s. The latest version, 1.5.1, can jailbreak 3.1.3. If can also unlock a iPhone (if on the appropriate baseband). Now, sn0wbreeze isn’t for everyone. While it does allow for customization, such as adding custom Cydia sources, Rock, boot logo, recovery logo, etc, it may be better and easier to use redsn0w.

You can download sn0wbreeze from sn0wbreeze.info. You can then download it. The rest of this post will show you all of the screen available to your for jailbreaking 3.1.3 using this tool. But, we do recommend redsn0w as the primary jailbreaking tool. Why? Well, for one, it doesn’t require a restore, and it doesn’t change the default wallpaper (earth wallpaper). AND it’s faster!

Sn0wbreeze works on the following devices:

• iPhone 2G
• iPhone 3G
• iPhone 3GS (old bootrom)
• iPod Touch 1G
• iPod Touch 2G (non MC)

If you do have a iPhone 3GS (with the new bootrom) or a iPod Touch 2G/3G with a model number beginning with MC, you can still used a tethered jailbreak. If you still are unsure whether or not you fall into this category, check out f0recast, a free and small tool for Windows that tells you if you are restricted to a tethered jailbreak.

Sn0wbreeze has the following system requirements:

• Windows XP, Vista, or 7 (32-bit or 64-bit)
• .NET Framework 2.0
• 512MB of RAM

You’re going to need a stock copy of the 3.1.3 firmware. You can download it for ALL devices here.

So once you create your jailbroken IPSW, you must put your device into DFU mode (use DFU mode helper in sn0wbreeze), and shift+click on Restore in iTunes. If you get a 1600 error when restoring, you’ll have to use iREB to do some iTunes trickery.
