Now your iphone can get even more usefull! Want to know what song is playing on the radio? 
With this great hack, you can find out that and more. Put your iphone near the radio speakers and check out the iphone screen. Admitedly, its currently in Beta. But if it works, then you will see the song, artist, and album all listed. (It samples the music for 5 seconds and then attempts to contact the id server).
Makes it easy to find that great song again – whether just to listen to or to download, right!
You can download it HERE. If you like it then let us all know how well it works for you.
