There's only one thing left to try...

I turn off my iPod that's plugged into the headset (not "Ride of the
Valkyries", but Amy LaVere)... silence. Wow. Cool. Plug back in, "podunk..."
Somehow the combination of iPod, wire and LightSpeed 30-3G was acting
as a radio (a very crisp, loud radio) picking up multiple frequencies
at once. I wish I had written down all the airport names so I could see
how many I was hearing, but it was quite the cacophony. I called LightSpeed
and the guy there had never had that reported before. I said I'd post
to a newsgroup to solicit other reports. Anyone?

Clearly your personal eletronic device is causing interference that endangers
the safety of the flight. The PIC or aircraft operator will have to forbid
use of the device.
