When I updated to GM on both my iPhone 5 and iPad 3 it showed my mail apps as having approximately 5000+ unread emails. Assumes its picked up everyone on my mail server and it was funny at first but how to do clear it? Tried going in and then doing 'mark all' but it only seems to select the emails you can see at that point and not all so? Any suggestions? It use that you had a choice of how many emails to download at a time but that seems to have disappeard?
