title: How to play a tone on iPhone
body: <p>Is it possible to easily play a tone, or series of tones on the iPhone (like morse code, beep beeeeeep beep)? </p>
  
  <p>Is there any sample code out there that would point me in the right direction?</p>
  
  <p>(I remember on the Commodore 64 it was about 4 lines of code !)</p>
