I have an iphone, a desktop and a Macbook with OF on each. I HAVE been using Mobile Me for syncing with no problems. I just tried the DISK option between the desktop and Macbook and it's MUCH faster. Is there a way to have the iPhone continue to use Mobile Me and the Macbook and Desktop use DISK? I've played around a little and it doesn't seem to work but maybe I'm doing something wrong. I assume there can be only one MASTER sync file but hoping, maybe, there can be a few that keep tabs on each other. Am I dreaming?
