Airfloat not really new, as it was first published in the AppStore, from which it was removed a year ago. However, the project, now reappears through Cydia.
Airfloat, is a tweak that after installed, we can find an icon in the Springboard (as if it were an application) and when we execute, we can activate AirPlay receiver.
With this, we can turn our device into a receiver with AirPlay, and send for example, audio from iTunes to your iPhone from an Apple TV from an iPad or another iPhone.
Airfloat you can download it for free on Cydia from the repository BigBoss
