Well they added iPod Touch 2G compatability a while back. But I still can't see a use for it. So I thought about it, and realized that it would be perfect if you could save the audio clips to analyze later when you were in a network. I can't see myself ever being able to use this without this..
They already have that feature it saves the clip and when you click on it later when you have a connection it will name you the song.
