Are the only programs that can sync Outlook, ACT!, Lotus Notes, and Lotus Organizer?
I'd like to keep my phone updated w/ my calendar events and such from my desktop program (MSN), but I'm not sure which programs are compatible. If those are the only ones, would anyone have a recommendation?
I'm thinking about starting to use Outlook for this purpose, but want to clarify any possibilities first.

I thionk it does Palm, too but OUTLOOK is the Blackberry's strong suit!

I am not fan of OUTLOOK but corporate America loves it!
