On my iMac I enter birthdays for some of my contacts in address book. When I open iCal on the iMac, it shows the birthdays. But even after I sync the iCal with my iPhone, the birthdays don't show up on the iPhone iCal. On the phone, I press "calendars" and there is a list "From My Mac" all checked (Home, Calendar and Work) and below, under "Other," it lists "Birthdays" and that is checked also. So what am I missing?
