The iOS sdk has two functions that would vibrate the iPhone. But Vibration hardware is present only on iPhones. So how will you alert your user who uses the app on iPad or iPod touches? Clearly, checking the model is not the way to go. There are two seemingly similar functions that take a parameter kSystemSoundID_Vibrate

AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

Both the functions vibrate the iPhone. But when you use the first function on devices that don’t support vibration, it plays a beep sound. The second function on the other hand does nothing on unsupported devices.
