Determine at runtime if the application is running on mobile

[Cristian Spiescu]

Hello,

I'd like to know at runtime, if the current application is running in 
web mode (in browser) or as mobile app.
Is there some kind of property that I can use?
I have looked at Capabilities class, but I'm not sure it helps. I see 
that there is a "playerType" setting, but it doesn't seem to 
differentiate AIR from AIR on mobile.

Thanks in advance,
Cristian.
