Just got a Motorola Droid, my first smartphone. Smack dab in the middle of my main screen is a big white box that says "No upcoming calendar events". I use Google Calendar quite a bit so at first I thought this box should synch with that. But when I select the box it asks me to configure an Exchange account. What the heck is Exchange? I've never heard of it before. Will setting up an account with that allow me to display events on my Google calendar? If not, is there a way to remove this box entirely and/or replace it with something else that will display my Google Calendar events? Thanks!
