I just picked up the Motorola RAZR for Cingular.

I've noticed something peculiar. This phone radiates a ridiculous field
around it, causing radio interference whenever a call or text message is
about to come in.

If the phone is within 10 feet of a radio, you can predict a phone call or
text message about 2 seconds before it actually arrives because whatever you
are listening to becomes garbled with digital RF static.

Anyone else notice this?

stop following me.

Ah, GSM. so it's a cingular thing, not a RAZR thing? Got it. I've been a
sprint guy for five years...

Service is pretty good. I think Cingular has better coverage in my area
(i.e., it works well in my living room and basement when sprint didn't), but
i experience more occasional static than i did with sprint, almost like
Analog static.

This is a nice device, and since the motorola v551 is a smartphone, we
tested and found it works great with an Internet connection and our s/w
from Orb Networks - and it's free. If you run this s/w on your
broadband connected XP PC, you'll be able to see and/or hear any of
your content on your phone like your music, videos, your photos and
even live TV (if you have a tuner in your PC). It streams this to
other devices too, any internet connected PC, PDA, etc...

Once and for all...

This interference is a result of the frequencies used by GSM. If your GSM
handset is near the audio device (speaker phone, stereo, mp3 player or
almost anything with a speaker), you're going to get these sounds whenever
the handset transmits. This occurs periodically when the handset and the
cell site "handshake". That is, the cell site interrogates all handsets
within range and exchanges a small amount of data. Something like (cell
site) "..whomever is out there, identify yourself?". (handset) "...I'm
here and available. My number is xxx-xxx-xxxx".

Also, when someone calls your cellphone, the cell site broadcasts a data
stream to all handsets, looking for yours. Your handset then transmits a
short burst of data, identifying itself. (this is why you can sometimes
tell when the cell phone is about to ring). Then the cell site sends a
ringing signal and your handset rings.

During the time you're talking, the handset is transmitting, so the
interference continues.

Generally, all GSM handsets should cause about the same amount of
interference. The variables are; 1) distance between the handset and the
audio device, 2) shielding of audio components inside the device being
interfered with.
