Exploiting the iPhone 4

One aspect of the jailbreak scene that always seemed like black magic to me, though, was the process of jailbreaking itself. The prospect is pretty remarkable: take any off-the-shelf iPhone, then enact obscene rituals and recite eldritch incantations until the shackles drop away. The OS will now allow you to run any code you point at it, irrespective of whether the code has gone through Apple's blessed signing process, paving the way for industrious tweak developers like myself.

A few weeks ago, I got a hankering to remove this shroud of mystery from jailbreaks by writing my own. One caveat: the really juicy work here has been done by my forebears. I'm particularly indebted to p0sixninja and axi0mx, who have graciously shared their knowledge via open source.

The fact this isn't a switch to flip in iOS somewhere is idiotic and will soon come to an end thanks to the EU, but at least it enticed some very creative and gifted souls to learn and experiment.
