2.3.3 seems ok. I don't like the apps arrangement now. The downloaded apps are mixed/sorted within the built in apps. Before they were at the end of the group and easy to determine which apps had been added.
I have also been getting Vlingo force closes a number of times. If I power off, wait until the vibrate cycle, then power it back on. Its ok for a while (day or two), then again. I am not certain why. I don't use it or lauched it and it wasn't running.
