Is there any application that will let me group my contacts? On my old Palm E2, I could classify each contact, Work, Personal, Business, whatever I wanted. Then I could view the type. I can't figure out how to do that on the G1. And while I'm at it, my E2 also let me color code events on the calender. I notice that the G1's calendar does have a blue color for events, but I didn't pick it. Is there a way to change the color coding?
