Starfish Software free from Yahoo... (Score 2, Informative)

You can download some quite excellent free (as in beer) software from Yahoo made by Starfish (remember Borland???). It's called TrueSync.

I use it to synchronize: Outlook (yeah, yeah, yeah, it's for work), Pilot, Yahoo Calendar, Yahoo address book and StarTAC phone. It's Win32 but has lots and lots of available modules.
