So as suspected when I installed the new Security patch released by Microsoft for SQL 2005 sp2 that I mentioned this morning my build number has indeed shot up to 3233.
This places me somewhere between CU6 and CU7. Build 9.00.3228 was CU6 and 9.00.3239 is CU7.
So just bear in mind that when you plop on your patch you are actually taking a number of other fixes through with you. Test...Test... Test...
If you are interested in seeing what published builds are out there I know of no better resource than sqlsecurity.com's version database which you can find here.
