You're comparing apples and oranges.

The advantage of the Snaptrack system is that it's a hybrid system for
locating the phone.

The GPS applications you can run on a PDA phone are unrelated to LBS or
E-911. It's true that some of the GPS chip-equipped CDMA phones can run
other GPS applications, but there are also GSM phones with that capability.

It's in LBS services that require a high-degree of accuracy that the
CDMA carriers have an advantage. Personally I'm of the opinion that it's
really unethical to watch every move your employees make, but others
argue that since you're paying them, you have the right to track their
every move. Obviously the users of LBS and the service providers have
the latter opinion.

You'll get no argument from me that it sucks that you can't use you're
older phones on CDMA networks. Actually you can use them on some MVNO
networks, such as PagePlus. I also despise what companies like Verizon
do by defeaturing handsets to turn off functionality that the
manufacturer included. There are no saints here.

That's what you're doing.

The advantage of U-TDOA is that it's a system that works with _any_
phone.

There isn't actually a meaningful difference in LBS.
