Just over six months ago, well-known hacker George Hotz, a.k.a. Geohot, joined the straight and narrow and got a day-job at Facebook.

However, word has it that he's already gone. Business Insider reported today that Hotz left Facebook and is back to hacking in his free time.

This time, though, it's legal hacking.

Last Saturday, Hotz attended a Backplane hackathon, according to Business Insider. Backplane is a social startup that heralds famous investors like Google's Executive Chairman Eric Schmidt and pop-star Lady Gaga.

Hotz first became known for creating software to jailbreak iPhones in 2007 and later allegedly hacked into Sony's PlayStation 3. Sony later sued Hotz arguing that he violated the Digital Millennium Copyright Act and the Computer Fraud Abuse Act. The case was settled last April.

During the Backplane hackathon, Business Insider said that Hotz built an app that lets users see their Facebook friends on a map. However, his app lost the hackathon to a group of high school students.

The reasons for Hotz's departure from Facebook aren't yet known.
