The PwnageTool update comes alongside redsn0w 0.9.6rc15, but PwnageTool differs from redsn0w in that it allows Mac users to create customized versions of their IPSW. This is a necessary procedure for iPhone users who wish to preserve baseband and some carrier unlocks. If you are just looking to jailbreak your device, redsn0w is easier, but does not offer the ability to preserve baseband with custom IPSW.
