Having upgraded my iPad2 to iOS-5, I've now got the new Reminders app. When I open it, I see a list of MAC addresses on the left hand side under, "Yahoo!" (I assume it says "Yahoo!" because my Apple store email is Yahoo) and above, "Reminders".
What are these MAC addresses listed for?
Note: my iPad is not one of the listed MAC addresses.
Note 2: these Mac addresses also appear in my list of calendars!
