You can't download your contact list from your N70, but you can add them manually.
Make a new text document (you can do this on your PC first) and name it :-
contacts
then add your names and numbers like this :-
"Russ","01254111111"
"Russ Work","01254222222"
"Russ Mobile","07777111111"
Just make sure you put all the "","" as shown above.
Then copy it to your memory card (you should also see 2 other text documents - named called & callers.
Hope that helps
