Can you delete "suggested" email addresses?
I've checked on my Mac (to which the iPad is synced) and the unwanted Smiths are no where to be found -- not in my Address Book. Also on my Mac in Mail I've clicked on Window>previous recipients and made sure the unwanted addresses aren't there either. (Also on my Mac these unwanted Smiths do not show up as suggestions the way they do on my 'pad).
On the iPad I can't determine any way to delete them. Any ideas?
