I downloaded these tones from a wap site which i've used for quite a while now...i downloaded them to my nokia 3220 and i could send them via mms and i also downloaded them to my nokia 6230 and i could send them via mms and bluetooth but i download the same ringtones to my nokia 6680 and i cant send them...when i view details it says the format is "audio/midi"...why cant i send them??
