The iPhone Dev-Team has released UltraSn0w version 1.2.3 for the iOS 4.3.3 firmware to go along with the updated PwnageTool 4.3.3, RedSn0w 0.9.6rc15 and Sn0wBreeze 2.7. If you’re interested in unlocking your iPhone on iOS 4.3.3 you can do so by downloading this updated version of UltraSn0w through Cydia. It’s important to note that no new basebands are supported in this update. This, once again, is simply a compatibility update and nothing more.
From the iPhone Dev-Team’s blog:

For those of you new to unlocking, UltraSn0w 1.2.3 supports the following baseband versions:
If you do not have one of the baseband versions specified above, then you cannot unlock your iPhone. If you do have one of the baseband versions specified above, however, you can head on over to Cydia and download/install UltraSn0w 1.2.3 and you will have an unlocked iPhone.
