Comment(by waffleIron):

 I'm having a similar problem with my Freerunner.  The interference is
 mainly heard by the other person.  I've noticed that if my fingers are
 touching the headphone jack, the gps port, or the usb port (in order from
 greatest to least effect) the interference gets worse.  If I put my
 fingers flat on the back of the phone (from the battery to the lanyard
 hole) the interference drops off to almost nothing.  This is all without
 the headset.  With the headset in the noise is completely unbearable.
 Also, this is all without the SD card.
