I had a black GS3 from Verizon but had to dump Verizon and go with T-Mobile (sadly Verizon is the only US carrier that offers a black GS3).
Anyhow, the black GS3 is an amazing looking phone,,, the black version looks about a billion times cooler than any of the other colors.
Why Samsung limited the carries or the number of black GS3's for release is a mystery and very frustrating.
It would seem like a no brainer to offer the GS3 in black,,,,,, perhaps Samsung didn't want to offer a "perfect phone" for the USA,,,,,,, gotta ruin it in some way so bring it out in blue and white,,,, that should hobble such a great phone nicely.
