Ooookaay, picture time.

From SDRman's post, I thought he was suggesting WiMAX could connect to the nine pads below. So my comments have been referencing that. The seven pads under the battery look like a cluster of seven pads in my N800; I thought these were the serial console, but not sure. The four pads are not quite the same layout, but I still identified them with a cluster of four on my N800. I was thinking JTAG, as I'd heard there was a JTAG interface, but I haven't really looked into this stuff much, having heard that it was a battery hog. (Both these clusters are accessible through shielding cutouts on the N800)

None of these look like speaker terminals to me, but I don't really know...
