Use a Red Bull can as a radio interference shield

Yes, someone has fashioned a "shield" out of an emptied and carved up Red Bull can, and supposedly it works like a charm -- just fashion it around the dock that came with the iPhone, use a little doublestick tape to make sure it stays on there (and I would maybe put some around the edges, too, so you don't slice your fingers open every time you pull the iPhone off the dock), and no more buzzing sound.
The maker does wonder if it would affect the actual signal of the iPhone at all, but it hasn't so far. If you've got a Red Bull can around to cut up and are driven as nuts as I am by that buzzing noise, here's your makeshift solution. The other option is to buy speakers that don't buzz, of course, but this seems a lot cheaper.
