Does anyone know if it's possible to see on an iPhone 4S if it is connected to GLONASS satellites (either through an API call or in the settings)?

GPS/GLOSNASS/GALLILEO work by sending time signals, there isn't really a "connection" to a GPS satellite. Then there is the AGPS/Wifi GPS stuff which gives you even more information. All these sources are combined mathematically to estimate spacetime coordinates.

What the iPhone API exposes is the estimated accuracy of all these sources combined.
