I installed WM2003 on my MPx200 and, I am wondering if I can use midi's for ringotones. I have tried putting several on my phone and they show up in ringtones just fine, but when I attempt to play them the phone just goes "beep". Is there any software I need for my phone to play midi's? or am I just sol? Using WMA's is great, but the space consumtion is quite high (1 - 3 megs a song). Any help would be greatly appreciated.
