iPhone Speaker Interference Foiled

I don’t know about you, but I grew increasingly discontent with the constant interference emitting from my iPhone through my computer speakers.

After a little research, it turns out that this happens with most AT&T phones and there’s a quick fix – albeit a bit of a duct tape-style solution.

Simply take a sheet of aluminum foil, roughly about 3 x 5 -inches, and leave your phone on it while working at your desk. Or, if you leave it in the cradle, use the foil to create a backdrop.

It works, and in my case, it has completely eliminated the problem.

Nice. How does it affect your reception? I believe the two are probably tied together. I have found also that by positioning the iPhone differently (like in the car), you can “change” the directions of the waves and reduce the interference (TDMA)

I did a review of some speakers that don’t react to TDMA noise: http://weblog.techdad.net/2008/02/20/review-of-dlo-portable-speakers-for-iphone/

Next you will be telling me that you also have to wear a tinfoil pyramid hat to boost my reception AND block the interference. (grin)

So far we have 75 tested calls, full bars, 0 missed! I have killer speakers so a 3 x 5 piece of foil vs. buying new speakers is my bet for now!

I am *so* looking forward to this solution making my mornings calmer. I listen to NPR as I wake up, and the interference drives me nuts.

Why is it just AT&T phones? Maybe the wackos with the tin foil hats are onto something after all ;-)

Julie, it’s a problem related to GSM phones vs. CDMA.

Yes, this has nothing to do with AT&T or the iPhone…it’s the frequency that GSM uses in the US. Better speakers should shield it and I supposed the aluminum foil could be doing this too.
