If you’re already jailbroken at 4.3.3 (by either redsn0w rc15 or custom IPSW), you can install this fix simply by running redsn0w rc16 over your existing 4.3.3 jailbreak. Just uncheck the “Install Cydia” option and check any other options you want. The fix will be installed no matter what you’ve selected. This is safe for even ultrasn0w unlockers to do (because redsn0w itself won’t update your baseband…only an iTunes stock IPSW update/restore will do that).
Here's our how to Jailbreak iOS 4.3.3 tutorial, with a video walkthrough, if you want the step-by-step.
The bug was smashed by @i0n1c. Other improvements include removing the need for Windows 7 and Vista users to set their CPU affinity -- they can just run as Administrator in WinXP compatibility mode now.
