Danger's servers also keep the Sidekick in synch with a personal Web site that lets you importcontacts and calendars from desktop programs like Outlook.
That's because a lot of core functionality is still missing from the OS, such as the ability to play music files or import real-life contacts, and there's a long way to go if it's to be signed off as "code complete" in October.
Once the initial import is done I setup my Google account on my Droid so that it triggered an automatic synchronization of calendar and contacts with Google.
