As of yet, I have not built entries in the standard "contacts" app. However, I have been receiving and sending emails on my iPad. I have noticed that the addressee's are saved somewhere (but not in contacts) because when I begin typing in the "To" prompt it pops up a set of addressee's that contain the letters I just typed. Does anyone know where this information is stored and how you go about editing them? There are a few that I would like to delete and alter a few (if I create a bad addressee it too is stored).
