Does anyone have an idea, how I can track or keep an account of how much *time* my iphone spends accessing data services? (Excluding WiFi, of course). I am not talking about Settings -> General -> Usage! That only shows the MB. Apparently, there are some tariffs in Germany, where the costs for data services are not calculated by the MB transferred, but by the *time* spent. All kinds of pointers, hints, suggestions, will be appreciated. Regards, Gabriel.
