When I was using Nokia N95, my favorite calendar app was Papyrus (sbsh.net). There were category icons on the monthly view. With this, I could easily tell what I have for the whole month. The Hero's built-in calendar only shows gray triangles when there are events available. Is there any third party app I can use? The app must fulfill these two conditions: 1) Can have category icons on monthly view. 2) Can sync with Outlook.
