Two men who allegedly broke into AT&T’s computer systems and stole the email addresses of early iPad owners were arrested Tuesday by the Federal Bureau of Investigation. The break-in made headlines last summer because some of the 114,000 email addresses were subsequently published by the gossip website Gawker and contained some high-profile names, including New York Mayor Michael Bloomberg and former White House Chief of Staff Rahm Emanuel. Andrew Auernheimer, 25, of Fayetteville, Ark., and Daniel Spitler, 26, of San Francisco were taken into custody Tuesday.
