Hi I just got an AT&T Pre3.

It was strange and frustrating that if I make a normal outbound call, the bluetooth headphone does work, and the sound is transmitted to my headphone.

but if I make a skype call, the bluetooth headphone does not work.

also if I got a incoming call, the BT headphone does ring, and if I press the receive button on the headphone, the call connects, but then the call isn't transmitted to BT headphone either.

Is it just my phone or this is a common defect?

Thank you!
