Jailbreaking iOS 4.3.1 with PwnageTool 4.3

PwnageTool and Redsn0w have been updated, and both allow jailbreaking a range of iOS devices without tethering. This walk through covers PwnageTool 4.3, with another covering Redsn0w to follow. The main difference between the two apps is the method of jailbreaking. PwnageTool makes a custom Firmware file that iTunes puts onto the device. Redsn0w jailbreaks a device after iTunes has installed a standard Apple Firmware.

Before starting a jailbreak using PwnageTool or Redsn0w you need the correct firmware for your device. I used a great guide at iClarified that links to every iPhone firmware that has been released. My iPhone is a 3GS so the firmware I wanted was the 4.3.1 (3GS): iPhone2,1_4.3.1_8G4_Restore.ipsw. Once downloaded and placed on my desktop I launched Pwnagetool 4.3.
