I have a SGH 225. It was working perfectly fine until I put in the headset from another Samsung phone. And now, I can't hear any sound from the phone, nor do the keys make any sound. When I dial or receive a phone call, the person on the other line can hear fine, but I can't hear anything on the phone. Does anyone know how to fix this?

thanks
