T230 MIC problem

Please help me with this one:

Sony Ericsson T230 was dropped on the floor, and
somebody was trying to repair it after that.
Microphone doesnít work, one of the little BGA chips
near bottom connector is missing.
As you can see on attached picture, one of the
contacts for this BGA is broken.

I was trying to get full schematics of T230 but
without any luck.

Please help me: which contacts of this BGA I must
connect with shortcut wire? (I know that this IC
is only some kind of electrostatic protection).
I donít have this IC, so I cannot check itís
connections with multimeter. If you have one,
please check which pads are connected to which ones.

If you have full or partial schematics, please send
it to me (or give me link to download them).

This phone is important to me, please help me.
