This is probably a stupid question, but I don't get it On the home screen of the iPhone, down the bottom, there is a "Mail" icon. Then the icon is marked with a number. I had presumed that this is the number of unread emails I have, but this is not correct. Nor is the number of emails I have in my inbox. It is not doing much good as an indicator of whether or not I have new mail, so I would like to make it more useful to me. Thanks! PS, "Mail" is linked to my Gmail account if that matters.
