+Because the "official" reference designators used by the original designers of
+the T60N925 board are unknown (no schematics cound be found and there are no
+refdes silkscreen markings), we have to invent our own new refdeses as part of
+the reverse engineering effort.  Here are the refdeses I have assigned to the
+major components:
+
+Connectors on the battery/SIM side:
+
+J1 = USB connector
+J2 = headset jack
+J3 = battery connector
+J4 = SIM socket
+J5 = camera connector
+J6 = loudspeaker connects here
+J7 = GSM antenna test connector
+J8 = WLAN antenna test connector
+
+Connectors on the display/keypad side:
+
+J9 = LCD connector
+J10 = keypad board-to-board connector
+J11 = debug FPC connector
+J12 = vibrating motor connects here
+
+MIC1 = microphone
+
+Contact pads on the battery/SIM side:
+
+PAD1 = GSM antenna connection pad
+PAD2 = associated ground pad
+PAD3 = WLAN antenna connection pad
+PAD4 = associated ground pad
+
+Contact pads on the display/keypad side:
+
+PAD5 = earpiece connection pad, left as seen from the front
+PAD6 = earpiece connection pad, right as seen from the front
+
+Pushbutton switches:
+
+SW1 = volume up
+SW2 = volume down
+SW3 = camera button
+
+Major ICs on the battery/SIM side:
+
+U1 = Calypso
+U2 = TWL3014 (Iota)
+U3 = Marvell 88W8385
+U4 = GSM RF transceiver (TRF6151)
+U5 = GSM RF PA (SKY77328-13)
+U6 = GSM antenna switch
+U7 = Marvell 88W8015
+
+Major ICs on the display/keypad side:
+
+U8 = S71PL129NC0 flash+RAM
+U9 = SPCA552E
+U10 = LSI ASIC
+U11 = W56940 (ringtone chip)
+U12 = CP2102
+
+Crystal oscillators:
+
+Y1 = xtal in the GSM RF shieldcan
+Y2 = xtal in the WLAN RF shieldcan
