A 26-year-old man from San Francisco, Daniel Spitler, has plead guilty to charges of identity theft and a conspiracy to gain unauthorized access to computers, according to the Wall Street Journal. Spitler, along with Andrew Auernheimer, was arrested in January for creating software used to attack AT&T servers in June 2010 and steal the email addresses of iPad owners. Auernheimer is in the middle of plea negotiations; Spitler could face up to five years in prison on each charge, and will be sentenced on September 28th.
