I'm moving this one to the hardware list since the topic is now more suited.

At times like these I wish the component placement file was searchable like 
the schematic. I would expect it to be near U1701, to the gps side of the 
battery and headset connectors, but so far I haven't spotted it. There's a 
pair of pads unlabelled between C1764 and H-TP1704 that seem a reasonable 
size and location but could be something else entirely.
