Lost "contacts" from main group, i.e. All Contacts
I was deleting contacts from a group "X", for example, in Address Book. Then, to my surprise, I found those contacts missing from the All Contacts list which means that not only did I delete certain contacts from the group but also from the main contact list. Is there any way to get them back? I tried going back to email and started typing in the name of one or two missing contacts, and they are still in the memory. How can I get them back into Address Book?
