Today PwnageTool 4.3.3 has been released by iPhone Dev Team to provide untethered jailbreak for recently released iOS 4.3.3. Besides preserving the baseband to retain existing unlock, Pwnagetool also allows you to hacktivate your iphone, add custom boot animations and custom packages.
Here is the step by step guide to jailbreak iOS 4.3.3 untethered using PwnageTool 4.3.3. It is to be noted that Pwnagetool works on Mac machines only. The windows users will have to wait a little longer until iH8snow releases an updated version of Sn0wbreeze, which does the same job on Win OS as Pwnagetool doesn on OS X.

Unzip and launch Pwnagetool 4.3.3.
Select Expert Mode. Now select your iPhone and click the blue arrow to continue.
Browse for iPSW file (iOS 4.3.3) which you have already downloaded in Part 1. (Make it sure that iPSW file is placed on desktop)
Now hit the Build button to cook the custom firmware and save it on your PC.
