The Grinn Productions blog has written up a tutorial for incorporating Google Calendar with Microsoft Outlook. Why might you want to do that?
Well, if you’re the author it’s because “not even Google can integrate a web-page to your Bluetooth phone.” So, using an open source program called Remote Calendars, the post details how to set up Outlook with Google Calendar to do just that. Keep in mind that you still can’t synchronize appointments from Outlook to GCal, but this is still a very cool way to squeeze a little more out of Google Calendar. If you don’t like the look of this but you still want to sync Google Calendar with your phone, you might also want to try out previously-mentioned GcalSync, which actually offers a two-way sync for supported phones.
