Last month, I rearranged my Address Book and deleted some contacts that I no longer keep in touch with. Things seemed to be fine until today when I was composing an email on my iPhone to a friend. On the recipient field, when I started to type a letter, some random contact showed up (which happened to be a contact that I removed before). I tried to use spotlight on iPhone to search for that keywords (the email address) in purpose of deleting it, but somehow can't find it. Is there anyway that I can completely remove the email address from that contact?
