What's the arrow icon when double-clicking home button?

My friend and I downloaded the iOS 5 software. However I noticed when my friend double clicks the home button in lock screen mode, the camera appears as well as an arrow with a square on top right hand corner. Once click, the option for iPhone speaker, iPhone and cancel appears. I was wondering if anyone knows how to get the icon.

That sounds like the airplay icon and that's what I get, when I click on it.
