Sooo. I've been exhorting the virtues of jailbreaking your iDevice. Not for cracked applications, but for the endless possibilities it offers! The ability for you to do what you want with YOUR device instead of staying inside Apple's white-walled garden. Growl for iPhone, SBSettings, Winterboard and many others add many features desired by users but denied by Apple. So yes, jailbreak = many possibilities.
However, the most exciting of them all is that iOS is built on a Darwin, which is a POSIX compliant OS.
In other words, an entire working Unix system in your pocket!
Of course, that only means one thing.
