I think I deleted the wrong Calendar app. I deleted the Calendar app with the blue icon and kept the Calendar app with the red icon. I'm thinking this because the Calendar app I have will not let me add other calendars from my google calendar. My friend has a rooted EVO CM7 and has a calendar app that looks similar to the one I deleted. On that phone you can easily add other calendars. So my question is, did I screw this one up? Can I somehow reinstall the Calendar app that I deleted? (Yes this is my first Android phone, so I'm still learning).
