I appreciate the help - but still no luck. I've got two email addresses with gmail - a personal and business. When I go to the calendar app on the Incredible and select more, calendars - all that I see are My Calendars, PC Sync and my personal email address. I've went into the calendar for my business email and went through the steps you stated for sharing. Since I was in the business email calendar, I added my personal email address as aperson to share it with. It wouldn't let me give my personal email address the option to edit and manage the calendar, just to view open and busy days. I received an email generated by google to my personal email address saying that my business email calendar had been shared with me. However its still not showing up on my phone.
Another dumb question - the basic calendar that comes preloaded on the Incredible - that's the google calendar correct? I've looked in the andriod market for a "google calendar" and have found nothing. Thanks for the help, in advance!!
