Just as the title says. Had a wee search but couldn't find anything on it (awkward problem to phrase/search for). Basically, if I get a new email and I open it on my Mac, it stays unread on my iPhone. I've left it for hours and it never syncs back up. However, once I open the Mail App, but don't actually read the email, it syncs up. On the iPhone, I have MobileMe set to sync everything.
