Is it possible for two users to share the same gmail calendar while maintaining separate email accounts with the iPhone 4S? Can you suggest how this can be accomplished?
Yes, just set the gmail account up as an exchange account and sync only the calendars on the one you don't want the email going to. Also have to go in at m.google.sync and permit the device to sync the calendar on both devices.
I do like the alternative above. Just share the calendar with the other email.
