IH8Snow has just released Snowbreeze 2.5 for 4.3.1 which is an untethered jailbreak like Redsnow 0.9.6rc9 and PwnageTool 4.3. Snowbreeze 2.5 for 4.3.1 allows you to create custom 4.3.1 IPSW files that will preserve your baseband for unlocking. If you don’t rely on a carrier unlock you should use Redsnow 0.9.6rc9 instead of Snowbreeze 2.5 for 4.3.1 as it is more intuitive and requires less jailbreak experience. Snowbreeze 2.5 for 4.3.1 is for Windows users only, so if you are a Mac user you need to use PwnageTool 4.3.

Note: Ultrasnow 1.2 doesn’t support iOS 4.3.1 at this time and you won’t be able to unlock your iPhone 3GS, 4 until it gets an update so be cautious and wait for Ultrasnow to get the update before you proceed with this jailbreak. ( If you rely on a carrier unlock of course )

Snowbreeze 2.5 for 4.3.1 supports the following iDevices:

• iPhone 3GS, iPhone 4
• iPad
• iPod Touch 3G, iPod Touch 4G

Follow the tutorial below to jailbreak your iPhone, iPad or iPod Touch using Snowbreeze 2.5 for 4.3.1 untethered jailbreak tool.
