Steve Wozniak and Steve Jobs

The Apple Inc. co-founders were early "phone phreakers" who used flaws in the telephone network to make free calls. Jobs, who assumed the handle "Oaf Tobark," and Wozniak, who took the name "Berkeley Blue," sold the "blue boxes" used for phone phreaking until they were robbed of one at gunpoint in the parking lot of a Silicon Valley pizzeria.

Jobs, who died in October 2011, had said the hacking experience was a necessary precursor to creating Apple. Wozniak now works as chief scientist for Fusion-io, a Salt Lake City-based computer memory company. He also competed on "Dancing with the Stars."
