BB FANS

I've been given one of these and have been trying to load things on to it.

I've managed to add a few Polyphonic Midi files but I know there was some MP3 files before I deleted them but does anybody know what the format is that it will play ?

I've got a short recording that I've like to use as a ringtone but so far I haven't got the file small enough to be able to upload it so I need to find out the Bit rate and sample rate that's acceptable. I've downloaded the user manual but it's of no use. And the Nokia software's Music Manager software isn't any help as it doesn't support this model. I have to use the File Manager software to transfer the files. Cool Edit Pro will recode the files for me.

Anybody remember playing with these phones when they were around ?
