I've just found this site where you can download a new ringtone everyday for free, and where you can sent free SMS to your friends, all over the world!!
This service is avaible if you have a nokia moblie phone.
I have just downloaded the ringtone 'Merry Melodies", and I can tell you that this is really FUN!
Unfortnunally, I have noticed that this site, which is owned by a French Company, is not fully translated :-( , but I think it's not a big deal for a non-french speaking user.)
