I can now transfer files on to the mmc card quite easily.
Unfortunaly the phone isn't believing it's an actual mp3 file so sadly can't play it.
On a different note, my old phone is a nokia 5510. Using the audio cable (The USB never worked at all) I could record atleast an hours worth of music. That phone doesn't have an extra memory slot so it's all base memory. Why does it require more space for a new phone to store music?? I certainly wasn't expecting to get less music on the phone than previously. Would it be worth (if I can fix the problem above) transferring direct from cd so they're stored in the AAC format? How much space does one minute take up in that format?
