b) iPhone 4.3.1 PwnageTool Jailbreak (Mac only)

Here are the steps for performing Snowbreeze Jailbreak:

First, download iTunes 10.2.1 for Windows, Snowbreeze 2.5 and iPhone 4.3.1 (links given at the bottom of this post). Then start the Snowbreeze app. Click on the blue arrow to move to the next step.

Browse for the firmware you downloaded. The app will now say “Identifying IPSW” and then “IPSW Verified”.

Once again, click on the blue arrow and select “Expert Mode” and then “Build IPSW”. This will take some time. In the meanwhile, make yourself a cup of coffee. If you own an iPhone that relies on unlock, make sure to select "Baseband Preservation Mode” instead of “Expert Mode”.

IPSW build process will now complete. It will now tell you to put your iPhone in DFU mode. To do that:

* Hold Power and Home buttons for 10 seconds
* Now release the Power button but continue holding the Home button for 10 more seconds
* You iPhone should now be in DFU mode

If you did the above steps successfully, it will tell you that “your device is now in PWNED DFU state…”. Click ok and start iTunes.

We are now going to flash the custom firmware to the iPhone. Click on the iPhone name on the left sidebar. Hold download the left shift key and click on the restore button. Then browse the custom IPSW you made. It will now flash it to your iPhone.

Note – Redsnow iPhone 4.3.1 is much more easier of doing jailbreak if your iPhone does not rely on carrier unlock.
