The
device works by using periodic nanostructures, 10,000 times smaller
than the width of a human hair, to separate the different
frequencies of light from each
other.
Two versions of the
device will be available to support various 3G network
frequency combinations (T - Mo, AT&T), but
other than the radio band differences it doesn't look like there are any spec changes between the two versions (pheww... same speedy processor, big 1500 mAh battery, etc.).
