Hi Ole,

I don't know whether Joerg has attempted the hardware fix yet. I finished
mine yesterday. Attaching the bead to the pad of pin 4 does NOT fix the GSM
buzz issue.

There are a couple of pictures.

Connector with pad 4 removed:

It's a little hard to see, in this photo the bead is soldered standing up on
pin4 with a jumper wire from the top of the bead to the side of the headset
plug.

With this change the buzz is just as bad as ever.
