Throwback: Kanye West + Ludacris + Game - Where You At? (The Whole City Behind Us)

Somewhere around 10 years ago, Boost Mobile came out with a advertising campaign titled "Where You At?" It was about using the Boost Mobile chirp to call people, often times with the phrase "where you at?". The focal point of that campaign was a song by Kanye West, Ludacris and The Game titled "Where You At? (The Whole City Behind Us)".
They also did a commercial/music video for the song, too. The two biggest things I want to know before I die aren't the secrets of the world, but 1) Did Nike pay Nelly to make "Air Force Ones" and 2) I need to hear the WHOLE story behind the making of this song and campaign. Getting three of the biggest rap stars in the world (at the time) to make a song for a corporate retailer? That shit must've been a monstrous headache between egos, creative control, money and timing.
