Mitnick
Here's what Wikipedia says about Mitnick:
"After a well-publicized pursuit, the FBI arrested Kevin Mitnick on February 15, 1995 at his apartment in Raleigh, North Carolina, on federal offenses related to a 2½-year computer hacking spree.[2]
In 1999, Mitnick confessed to four counts of wire fraud, two counts of computer fraud and one count of illegally intercepting a wire communication, as part of a plea agreement before the United States District Court for the Central District of California in Los Angeles. He was sentenced to 46 months in prison in addition to 22 months for violating the terms of his 1989 supervised release sentence for computer fraud. He admitted to violating the terms of supervised release by hacking into PacBell voicemail and other systems and to associating with known computer hackers, in this case co-defendant Louis De Payne.
Mitnick served five years in prison, four and a half years pre-trial and eight months in solitary confinement, because law enforcement officials convinced a judge that he had the ability to "start a nuclear war by whistling into a pay phone".[3] He was released on January 21, 2000. During his supervised release, which ended on January 21, 2003, he was initially restricted from using any communications technology other than a landline telephone. Mitnick fought this decision in court, eventually winning a ruling in his favor, allowing him to access the Internet.
As per the plea deal, Mitnick was also prohibited from profiting from films or books that are based on his criminal activity for a period of seven years.
Mitnick now runs Mitnick Security Consulting LLC, a computer security consultancy."
"Mitnick gained unauthorized access to his first computer network in 1979, at the age of sixteen, when a friend gave him the phone number for the Ark, the computer system Digital Equipment Corporation (DEC) used for developing their RSTS/E operating system software. He broke into DEC's computer network and copied DEC's software, a crime he was charged and convicted for in 1988. He was sentenced to twelve months in prison followed by a three year period of supervised release. Near the end of his supervised release, Mitnick hacked into Pacific Bell voice mail computers. Mitnick fled after a warrant was issued for his arrest, becoming a fugitive for the next two and a half years.
According to the U.S. Department of Justice while a fugitive Mitnick gained unauthorized access to dozens of computer networks. He used cloned cellular phones to hide his location and, among other things, copied valuable proprietary software from some of the country’s largest cellular telephone and computer companies. Mitnick also intercepted and stole computer passwords, altered computer networks, and broke into and read private e-mail. Mitnick was apprehended in February 1995 in North Carolina. When arrested he was found with cloned cellular phones, over one hundred clone cellular phone codes, and multiple pieces of false identification."

There is a great film about his jail time made by his friends but there is also a film which is completely rubbish and possibly liabilus (Track Down).
"A fan-based documentary named Freedom Downtime was created in response to Track Down."
If you look at what he did, he didn't really do much more than Steve Wozniak or Steve Jobs - they were also known to be phone pheakers though not sure if they hacked any systems (I bet they did though).
