Saw the Joybubbles documentary over the weekend at Sundance (online). Hope it gets a wide release. That Joybubbles was one of the early, pioneering phone phreaks is reason enough to be interested, but it's his big-hearted humanity that will stick with you.

Yea, I heard the #offthehook #2600oth radio #wbai and podcast folks talk about him over they years, since the 1980s.

Thx for the reminder about the doc at #sundancefilmfestival

Josef Carl Engressia Jr., aka: Whistler, later known as Joybubbles, was a blind phone phreaker with the extraordinary gift of absolute pitch. He could whistle a perfect 2600 Hz tone, the exact frequency needed to manipulate AT&T’s phone system. Without using any devices, he could seize control of long-distance calls just by whistling into the handset.

In 1971, Engressia became the first phreaker to face legal consequences when he was arrested and fined twenty-five dollars for phone fraud. Despite this, he remained a legendary figure in phreaking culture. Later in life, he legally changed his name to Joybubbles.

Long before the internet, some phone networks were hackable by playing a single tone at 2600Hz.

Whistled into a phone, it could grant you unrestricted access. Do you have the vocal chops to be an old-school phone phreak?

I built a web app to test your ability to produce the legendary frequency. You won't get free long distance calls but you will get some honor in the knowledge that you could have been a cool hacker. 😎

I am sad to say that I can only whistle up to 1100Hz... But my wife (a long time woodwind player) is able to consistently get it.
