How can I play music from my iPhone/iPad via AirPlay?

If you are using iOS-Version 4 or higher on a multi-tasking iPhone (3GS and 4) or iPod touch (3G and 4G), then you are able to use AirPlay (formerly known as "AirTunes"): 1. Open the simfy-App and start the Playback 2. Open the multi-tasking bar/menu by clicking on the "Home" button twice. 3. simfy will be minimized and the multi-tasking bar/menu will open and the Apps will run in the background. 4. Swipe the bar to the left twice to get to the volume and speaker settings. 5. You can transfer the signal from your device to the remote AirPlay-Speaker by using the symbol on the right. Important: This setting can only be used if WLAN is active and only if your AirPlay-compatible router (AirPort or AirPort Express) is connected to the same relay network. The audio port of the AirPort can be connected to your stereo system ahead of time. As soon as the signal has been transferred, you will be able to listen to simfy on your hifi-system.
