Sorry for the second letter. I just verified the GPS issue with 
grindars.
He says that BP does not communicate with GPS chip directly; both UART
and GPIO of the GPS chip are connected to AP. The only thing that will
not work with BP off is GSM A-GPS, which is trivially replaced if you
have WiFi connectivity or cellular data.
