So when none is checked the default is the address book at the top? If so I can always perhaps move all contacts from 1 to the other, etc.
Anyways, I think its solved with your help. My address book was already the selected one and adding new contacts upon GO's offering was adding to other address book. But I marked another address book then unmarked it (the wrong one), marked the one I want again and this time it seems to have understood and new entries as per GO suggestions are going to the correct address book.
