OK, so far everything has worked just fine. For some time I've used Dataviz's Passwords Plus in my Palm, Mac, and PC. Dataviz is apparently not moving into blackberry for now. I'm not positive, since one can't actually talk to anyone there. So, I'm looking for a program that will work in all three platforms and synch easily via the Tour. It must be encrypted and must export to a .csv file.
I've looked at Datavault, but it does not work in a Mac.
Verizon 9630, following long succession of cell phones and Treos.
Take a look at Splash ID. Not sure it will satisfy all your requirements, but it does have both Mac and PC clients, but I doubt the Mac client will sync with the BB directly (although with a Mac DM coming, it might in the future).
