DerrickTH,
I assume from your post that you have an early generation iPhone, by which I mean NOT a 3G iPhone(it has a brushed metal back). If this is the case, then I am very sorry to inform you that your iPhone model does not support A2DP(Advanced Audio Distribution Profile) which is necessary in order to listen to music through a stereo bluetooth headset. Apple has stated that they do not intend to extend service to older generation models for this feature.
