SignalR realtime and websockets from the app

Hi Guys, with the release of version 4, does mono / Xamarin.ios and Xamarin.android support websockets.

If we setup an app, in Xamarin.ios and Xamarin.android to use the SIGNALR component, and connect it to Azure, will it use websockets from the app or fall back to other transports like we have seen in the past?
