@coderus: Yep, I can browse through my address book when I select 'Add contacts'. Somehow most contacts are displayed multiple times, first only as numbers, then with the name and then some even for a third time in a consequent list. When I select 'Sync all phonebook', it just goes back to my conversation list and nothing happens. Same if I try to add contacts one by one. It seems like a contact is added to the list if I receive a message from them. Like my work phone number from which I received a message, is now in the list along with the groups.
