I just checked and there is an update to the W600i firmware. It says Cingular firmware update available. My firmware went from version R7B046 to R7CA017. It took around 15 min to update. Everything seems to be working fine. I noticed my bluetooth finally works with my Motorola HS-850 headset now. It updated Java from 6.1 to 6.3. The camera version went from 4.4 to 4.6. I am still trying to figure out what else it changed.
