More unsubstantiated bullshit, Vic.  Post the URL backing up this claim.

RIMM had one of its best seasons, ever.....a hair under 1.3 BILLION dollars
NET income to the shareholders.  up from $631,000 the year before.

I don't know if you can see that through those Apple-controlled glasses but
that's DOUBLE the NET PROFIT in 12 months!

Poor RIMM, how can they carry all that to the bank?!

I lived and worked in a screen room at the Metrology Laboratory of the
Quality Assurance Office of the Charleston Naval Shipyard (Code 132 for
those that collect code numbers) for nearly 15 years before it closed.

A screen room (electromagnetically isolated chamber) is NOT, I repeat
NOT anechoic, a chamber that has no RF reflections off its walls.  It
was never meant to be.  A screen room prevents external signals from
OUTSIDE the screen room from messing up the measurements INSIDE the
screen room, hence the name "isolated chamber".  This is NOT an
enclosure to test anything to do with antenna patterns, sensitivity of
receivers in certain directions, because any signal transmitted INSIDE
the screen room bounces off the metal walls (see the metal walls in the
picture of this dumbasses test chamber?  REFLECTORS) which prevents
measuring any signal generated INSIDE the screen room to detect deep
nulls, a poor antenna pattern in the wrong direction for good
reception/transmission.  To test these functions, you need to be in an
RF Anechoic chamber such as:

Here's a good explanation of how they function:

Here, you see a properly setup RF anechoic chamber for broad frequency
range testing of emitters (transmitters, unwanted emitters like
computers, etc.)

Here's a little one for certifying radiation from wireless devices like
routers.

Now, compare THOSE to a simple SCREEN ROOM (isolation chamber) made to
shield out external RF noise from OUTSIDE the room from the test INSIDE
the room...without the massive RF absorbing ferrite walls to prevent the
screen room from reflecting back RF generated inside the room.

All tests done on the phones to determine their antenna effectiveness
and make pattern graphs in any plane to detect offending nulls, poor
patterns MUST be made in an anechoic RF enclosure with absorptive walls
I've presented here.

I had to certify military stuff from the late 60's to late 80's before I
came to my senses and started my own company.  God you digital jerks are
DENSE!

The measurements inside the NON-anechoic chamber are USELESS!  They
might as well have been made in a microwave oven!
