The 'official' OS available changes with what carrier you have I believe? I have .78 on mine - was added by the desktop mannager software. I use Verizon btw.

If you do end up getting a storm here are the apps I recommend:
- WeatherBug - Weather report/weather alerts. Can use the built in GPS to give you local weather.
- Tiltris - Tetris app that you control using the 'tilt' feature of the phone (accelerometer).
- AP news - news app from AP.
- Youtube - use this to access youtube, instead of just going there in the browser since that will only load very low quality vids.
- StormLock - (costs ~$3) - Locks the screen while you are on calls. Without an app like this it is very easy to screw up a call if you hold the phone with your shoulder.

I found those apps on CrackBerry - there are more apps to choose from and its usually easy to find on the boards there if they are worth getting.
