Hi all,

1) Since sp-midi and midi files have the same file extensions (.mid), how does one find out whether a given *.mid file contains a midi or sp-midi content?

The content identification is needed so that one can assign the correct MIME Content type: audio/midi (for midi) and audio/sp-midi (for sp-midi).

2) What happen if the incorrect MIME Content type is assigned to the midi files? Would the ringtone still be accepted and played by the handset?
i.e. audio/sp-midi assigned to a midi content or audio/midi assigned to a sp-midi content

are the two mime content type inter-changable?

Much appreciated
Dave
