Phone freak (with an f) was the original term, in the late 1960s. When Ron Rosenbaum wrote "Secrets of the Little Blue Box" he made it into "phone phreak". "Phreaker" came a bit later (1980s is about right). Shameless plug -- I wrote a history book about this whole subject, "Exploding the Phone": https://www.amazon.com/Exploding-Phone-Phil-Lapsley/dp/08021... My website, such as it is, offers additional goodies, including lots of scans of original docs like FBI files: http://explodingthephone.com/ If you want more on Captain Crunch, see http://explodingthephone.com/search.php?q=draper&sort=releva...
