Fake Steve Jobs (journalist Dan Lyons) recently proposed that iPhone users today at 3PM EST begin gobbling up as much bandwidth as possible -- in protest of AT&T's shoddy 3G network performance. AT&T has since called the joke "irresponsible and pointless," and now even the FCC has chimed in on "Operation Chokehold." "To purposely try to disrupt or negatively impact a network with ill-intent is irresponsible and presents a significant public safety concern," the FCC tells ABC News. It added that "threats of this nature are serious, and we caution the public to use common sense and good judgment." Even Lyons seems to be backing away from the campaign, though judging from comments to his post by his blog's readers, AT&T users may not be listening.
