Phone feedback?!

[brn2ski00]

Does anyone else's iPhone cause feedback through their desktop speakers? Mine does all the time if its within 3 feet of the speakers.... kind of annoying. Any resolutions to this?

I use Logitech thx speakers -- bought back in 2002-03.

It is called GSM noise. It is common with GSM based phone because of the pulses of data that they use. Your speakers are not shielded nor have a frequency loop in them. You can fix it by running the wires going to the speaker through a circular magnet (either from Radio Shack or from the block from computer cables) or getting shielded speakers.
