Music for mobile phones

[eddu]

I am a bit newbie with this stuff. I've been asked to do some mono and polyphonic music for mobile phone games and need some advice.

do all polyphonic mobiles have an integrated GM player supporting progrma change, etc.or should i make a kind of special MIDI file?

Please can you point out some general considerations?

Thank you

The idea behind General Midi is that program # 1 is always a piano, etcetera.
