Hey all, I have tried to add mp3's and set them as ringtones on the new Nokia 6255. I am getting a "invalid file" message. However, the mp3 can still be played in media player. I have used a converter to transfer to .amr ext and still have "invalid file" message. After reading features on this model, it says that mp3's can be used as ringtones. Does anyone know how to set it up in group ringers? Before I actually buy this phone, I want to make sure it can be done. I can tansfer through infra-red and or bluetooth just can't use them even in .amr ext. I have trid to transfer to midi, but c'mon that sounds horrible!!
