Hi fellas,I have the Sony Ericsson W550i for over 1 year now and in the last 2 weeks it's giving me some problems.. W550i stands for a walkman type.. And whenever I listen to music and receive an incoming or outcoming call then I hear a terrible *beep* all the time.. The music stops like it should, but I hear something like a fax beep and on the other side of the telephone they can hear me, but the only thing I can hear is a beep.. I only have the problem when I have my headset on.. I sended out my telephone for a reperation and it seemed ok afterwards, but now I have the same problem again.. Any1 here has the same experience with it? Or even better, a sollution for this issue? I appreciate any help in hereYours truly,Patrick
