Umm... which line was racist? There was no mention of race or suggestion that a color was tied to a race.
They did mention the a specific model of the Yellow phone was sold out in the US, Hong Kong and Canada but that is hardly an indication and/or implication that a specific race is buying it.
To me it is an indication that this particular combination was under-produced.
Seriously? You couldn't sense the sarcasm in that?? Where is the sarcasm font when you need it?
