Does anyone know if there is an app that will allow me to use the same headphones I use with my iPod Touch to control music. They are Sony and were made to control the iPod. Right now they will Play/Pause the music with one click, redial with a double click and Voice Dial with a long press. I wish I could skip tracks and control volume with these so I didn't have to fiddle with the phone while it's strapped to my arm. Any suggestions?
