I have a Treo user complaining that the contacts in a personal address book keep disappearing. He created a book with his first name, adds contacts to it, and then syncs. It looks fine at first, but at some point (hours or days, I am not sure), all the contacts disappear. Unfortunately at this point the description is vague but I do not have more information at this time until I can contact the user. I will provide more info as soon as I can get it.

Has anyone heard of something such as a sync setting for GMS that could account for that?
