I can never remember this. More of a note to myself. I just got the new iPad (thanks wife!) and when I added my google apps account as an Exchange server, my delegate calendars did not show (for example, the shared family calendar).
All I needed to do was to visit m.google.com/sync from the iPad, log in, and I can select what calendars my device sees.
Great post/suggestion, and completely worth the minimal effort in the long run! I spent far too much time researching this on my own several months ago and didn’t understand why more people weren’t readily discussing this online.
