iPhone3G Playing Mono on A2DP stereo Headset

[sumeet911]

Hello everybody
I got this from dealextreme.Its a stereo headset but it doesn't seem to work with my iPhone 3G.

I paired it with my PC and it works great (in stereo mode) when playing music from my PC but when I pair it with my iPhone 3G it only plays in MONO mode.Everything else works fine.

Please suggest me how to fix this.

Update:

I found a way to fix it.I downloaded "bluetooth profile selector" from cydia and enabled A2DP profile for this device,Somehow it was disabled.

Thanks everybody
