But it _could_ issue reminders, set appointments, and send messages if channeled through google's servers couldn't it? I'm sure there are many iOS users like myself who point the default apps at Google's calendars and mail. If the app calls back to google and says "put x on calendar for authenticated user y" then it would show up in the iOS apps.
