Tlister:

i know this sounds crazy, but i did it and it works:

cut a piece of aluminum foil, 2x3inches, fold it in half (= 2x1.5 inches).
tape the fold to the back of the iPhone on the right starting at the bottom
so that i covers the lower black plastic part and most of the words on the
metal skin.

i had bad interference with the car radio.
so i taped this on the back, went to the car and had complete elimination
of the repetitive interference.

I'm a little confused on the point of that article: is it the iPhone's fault that it creates the static, or is Apple blaming the other devices (i.e., my computer speakers)?

My roommate had a Nextel push-to-talk phone a few years ago that would make my computer's speakers rattle briefly when it received a call -- if the phone was within 2-3'. The iPhone pretty consistently generates interference even when it's 4-5' away from the same speakers. I've never had another cell phone that did this at all, much less with the regularity or range of the iPhone.

Does that have something to do with the EDGE connection? The iPhone is the first one I've had that used EDGE or AT&T/Cingular's network; all my other phones have been Verizon.

Just curious where the fault lies. According to that article, it's my speakers and not the iPhone. If that's the case, is it just certain speakers?

Thanks.
