Both will work. I am using a circularbytebuffer.
Just remember to modify the read to feed the player the correct header.
The 9000, 8900 and 9700 are the devices I've tried it on.
The biggest problem is the buffering delay on the incoming audio when using OS 5.0....

Not sure if background or foreground matters and not sure if 2 processes or 2 threads matter.
CMDA or GSM may show differences. I am curious how come the phone application itself can fulfill full duplex. Maybe it's a little on the J2ME audio manager for CMDA devices. It seems ok on GSM devices.
