Wow, Joe. Welcome. I'm brand new too, so take anything I say with a grain of salt
My Visor Edge (also black and white
just died, and I too am a new BB user missing my Palm Desktop. Let me know what you find out about the desktop program. Some folks recommended google and yahoo, but I'm not fond of the internet-based calendar programs (like my privacy).
I was able to import my Palm data by syncing my BB to my laptop (where I had already sync'd my Visor before it died. I downloaded the new BB desktop from RIM (v. 4.3) maybe that made the difference? Don't know if it works with your model, but it worked for my Pearl (8100). There's a "switch device wizard" that made it work for me.
