So I installed EBook editor and it turns out that any edit I make to
this contact vcard is not saved AND I cannot delete it.

I looked at the libosso-abook API and there are some calls to check if
a contact is blocked or blockable but no API either to block or
unblock:
http://maemo.org/api_refs/5.0/5.0-final/libosso-abook/OssoABookContact.html#osso-abook-contact-get-blocked

Does this blocked mean the contact cannot be deleted ? Note that in
the API I could not find the meaning of blocked. Could the failure of
EBook to delete the contact be that the contact became somehow
blocked? If so how to unblock it ?
