PC World – Apple CEO Steve Jobs may have a reputation for being difficult, but his alter ego, Dan Lyons’ Fake Steve, may be even worse. On Monday, Fake Steve continued his attacks against AT&T’s reputation for poor service by encouraging readers to flood AT&T’s 3G network at noon this Friday in an attempt to cripple AT&T’s data network. Dubbed Operation Chokehold, Fake Steve calls on iPhone users across the country to run a data intensive iPhone application for one solid hour on AT&T’s 3G network. As you can imagine, AT&T was not happy to hear about this “digital flash mob,” as Fake Steve is calling it.
