[android-developers] location updates verizon

Is it possible to get network_location updates with Verizon phones? I could imagine that not, since Verizon is CDMA and there is no timing advance as in GSM for instance, so the network might not know the location at all. I am not sure though. I notice though that I am not getting anything from getLastKnownLocation when asking an ACCURACY_COARSE provider with a Verizon phone.
