While talking about ESD:
To me it seems, BATTEMP, headset-connector (i.E. HOLD, JACKINSERT), outer 
plane of touchscreen (XL,XR | YU,YL ?), and of course debug connector, all 
could use some ESD protection. As well as GPS-ext-ant, it seems (U7606,1. 
Yeah i know, RF).
Ok, i didn't check the specs of the CPU pins that get the impact, but IIRC 
there was a statement of 4kV ESD surge resistance for the GTA. I guess any 
complex chip will be better off not to take this.
