OK... I broke down and decided not to wait. I applied 5 VDC to the pins to see if it would charge.
YES!!! It does charge with Gnd on top pin (closest to power button) and 5VDC to the bottom pin. The phone indicated Charging and the current draw was about 1amp (will put a digital meter on current for more accurate charge current reading).

I felt confident that I would not damage the phone by reverse voltage because just probing the pins showed no voltages out (meaning they are probably internally diode protected). This would have to be the case because people drop their phone in their pocket with loose change and would hate to short the phone (and possibly ignite the Lion battery).
