Oh sure, we've got all three in Hong Kong too although I suspect PCS is 
pretty much gone though.

Huh? When I had a CDMA phone, people in elevators STARE at me while I 
keep yapping and those who recover in time will check their GSM phones 
for signal. Too bad nobody wanted CDMA and so Orange/Hutchison/now Three 
did not bother maintaining/expanding its network. Now I am on a lousy 
GSM network (Smartone-Vodafone) and my Nokia 6500 don't work in lifts.
