Pardon my nooby-ness. MuscleNerd just mentioned via twitter that the 4.3.1 ultrasn0w has been tweaked and should be good to go now.
For those that don't know, I am using my iPhone 4 on tmobile (4.0/01.59).
I am going to attempt the pwnagetool found here:

Is this the one to go with to keep my baseband and move up to 4.3.1?
