The rumors were true: Samsung is adding white as a second color choice for AT&T's recently-launched Samsung Galaxy S II Skyrocket, which means you've now got your choice of white or black for $249.99 on contract. Interestingly, this matches up with the HTC Vivid — the other device in AT&T's LTE handset premiere last month — which is also available in the same two colors. Look for it online and in stores beginning tomorrow, December 4th.
