How can I remove email addresses from Mail's autocomplete? How do remove or erase the emails that I use befor on iPad email, they are not on my contacts. As soon I start typing one email address I get a bunch of old address..how can I erase or remove that.
I've had this same concern and from what I understand Apple does not provide a method to accomplish this cleanup. There are many threads in Apple Support discussion board and they always end suggesting to email Apple the request for this ability.

However, if you own a PC, this gem popped up:

Can't delete Unwanted Email addresses, Auto-fill in saves them all !
