Oh, heh - might just be for the beta period, but the software is free - it's the wireless syncing that is $10/month.

Installed the software just now, and it's alright... doesn't adhere to the 770's Maemo distro though. For instance, adding a contact opens a new window, but clicking on the standard close X closes the ENTIRE app - there's a separate coded close box button in the app, on the lower toolbar. Weak!
