[SyncEvolution] two issues with Nokia 7020

I am syncing a Nokia 7020 over bluetooth, through sync-ui, and I ran into two issues: * General: The syncing process does not honor the one-way sync chekboxes. However I check only 'Send changes to...', the syncing is bidirectionnal. * Contacts: Postal mail addresses are transmitted from Evolution to the Nokia 7020, but not the other way: if a contact has been updated in the phone, after syncing its mail addresses dissappear from Evolution. Certainly Evolution knows of three types of postal address while the Nokia allows only one, but I suppose that wiping out all the fields that don't correspond exactly is not the intended strategy to cope with differences in formats. Any clue? Thanks in advance.
