Why Location Acquisition API (C++ side) does not support to determine technology information in s60 3rd edition ?

But as in JSR 179 specified that Location::getLocationMethod() returns the technology infotrmation also like (CelliId, Sattelite, shortrange).

So I want to know if JSR179 is implemnted by J2ME Symbian 9.1, it must have same support in C++ side also, why it is not like that?

PLz help.
