Has anybody got the CMIDIClientUtility working on Series 60 phones ?

The class has partial documentation in 2.1 SDK, but all headers & libraries are missing.

The libraries & headers seems to be shipped with Series 80 SDK, but using them in Series 60, will cause -5 (not supported) error.

So has anybody got this ever working ?
Or any other way of playing Sp-midi/Midi files from buffer in Series 60 ?
