I am working on a Qt and Symbian c++ project and I want more information than provided by centralrepository lib. Right now all I can get from it is GPRS Sent/Revived and WLAN Sent/Revived.

Is there another API that I can use to get the amount of data used by each application, like browser or VOIP applications?

I already tried using QNetworkSession but I had no luck with that.
