Chpwn, a popular developer of tweaks for jailbroken iPhones, is now working as an intern at Facebook.

Last night he announced the news via Twitter, "Just finished my first day as an intern at Facebook. Very excited."

Chpwn is responsible for many tweaks including: Infiniboard, Infinifolders, Infinidock, Overflow, Zephyr, Spire, AppSlide, VoiceActivator and more.

Chpwn is not the first high profile member of the jailbreak community to go work at Facebook. The famous hacker George Hotz also went to work for the company for some time last year.

Interestingly, Facebook is reportedly hiring former Apple engineers to help it build its own smartphone.
