Blackberry: NOTE: You must already have a google email account (sign up at www.gmail.com). You will also need to install google sync on your blackberry.

Once installed, the google sync setup will ask for your gmail account name and password. You will also have to scroll down to the bottom of the google sync options screen on the blackberry and make sure the (Your site) calendar you added to your gmail account is selected on the blackberry.
