Hi, can you have either MP3 or WAV ringtone to nokia 6630, ie where and which folder do you transfer them to and how to make them work etc...

Either can be used. Just store the ringtone to the phone, or mmc, and select it when setting the ringtone in the profiles.

Best to put them in c:\Nokia\Sounds\Digital or E:\Sounds\Digital on the phone.

Note that some operators, like Vodafone, have phones where MP3 use has been prevented.
