aGPS may use triangulation as part of its data sources, but that doesn't mean that all triangulation (or more accurately trilateration) methods = aGPS. What Google is using for this system is not requiring any use of any aGPS chipset. The program only needs the phone to pass on some tower information. Which means that it isn't requiring any intervention on the part of the assistance server for it to function. Which would be why Google is able to offer this service without getting permission from Sprint, Verizon, AT&T, etc.
If you don't trust Wikipedia, then maybe another article might educate you better.

Nice try on "might educate you better"... but that is not what we were debating... we were debating the differences between aGPS and sat based GPS. Yes, I know all about how Google tries to do LBS without using any "GPS type" data being supplied to it... it's not an original idea, it's already been done by Navizion:
"Navizon is a software-only wireless positioning system that triangulates signals broadcasted from Wi-Fi access points and Cellular towers to help the users find their way in most major metropolitan areas worldwide."

But my original statement still stands... think about this... if Google Mobile LBS is designed to work with any Windows Mobile phone, how come the LBS doesn't work on the Mogul? Why? because as I previous stated, Sprint has either locked down the API that needs to be queried by the software, or they left it out altogether. My vote is for the latter since not even Sprint themselves sells LBS for this phone.... why wouldn't they if they could make money?
Think about it...
