Why not use updatable CTEs?  That's what they're for.

WITH update_contact as (
   INSERT INTO contacts ( contact_id, name )
   VALUES ( nexval('contacts_id_seq'), 'Joe' )
   RETURNING contact_id ),
new_cont_ids AS (
   SELECT contact_id FROM update_contact;
),
insert_phones AS (
   INSERT INTO phones ( phone_id, contact_id, phone_no )
   SELECT ( nextval('phone_id_seq'), contact_id, '415-555-1212' )
   FROM new_cont_ids
   RETURNING phone_id
) ...

I think you get the idea.  On 9.3 or later, this is the way to go.
