Jumper(s) for U16 compass IC?

Hi all, I am currently trying to fix an iphone that has had some of the solder pads lifted under the compass ic (U16).

I have been trying to figure out from the schematics if there is a way for me to jumper these pads - the missing pads are B4, C2 and C3.

I have managed to get hold of the IC information sheet from the chip manufacturer, and as far as i can see pads C2 and C3 can be bridged with C1. However, B4 is the main output pin and i can't figure out how to jump it.

The schematics simply mark B4 as "SO" (serial output) but does not show anything further. Does anyone have any idea how i can jumper pin B4?

I don't know if I can help you, but if you find another device on the same I2C or SPI bus, you can use the same line.

On my device, the chip fell off during a repair mishap. Fortunately the only missing functionality has been the compass, and the phone isn't made upset in any other way.
