Overview

CTelephonyReader implementation illustrates how to get Network Name in S60 3rd Edition Device with CTelephony API.

The implementation is pretty simple, and when using this one only thing to do in calling class is to implement the callback interface and then to construct an instance of the CTelephonyReader.

Note: this code will most likely not work in the emulator, thus you should only use it in real devices.
