Skullphone billboard hack we saw yesterday had everyone at Engadget HQ pretty impressed with the corporate-pranking hijinks. Too bad it turns out that Skullphone is actually a phony (and total buster, we might add) who had to pay The Man (aka Clear Channel) cold hard cash to "glitch up" the digital billboards. According to Curbed LA (and our reliable tipsters / commenters), Skullphone paid the massive media conglomerate for one-day Los Angeles-wide ads -- there was no hacking involved at all. From now on, he should just leave the signage-goofing to the pros, or at least make it clear there's some money changing hands. Fool us once, shame on you... and... we won't get fooled again.
