PSJailbreak cloned, released, freely available
Found on Ars Technica on Tuesday, 31 August 2010
You'll need the code, a PlayStation 3, and a USB microcontroller in order to open your system. Oddly enough, sales of such devices seem to be in the middle of a spike.
Once the PlayStation 3 was hacked it was only a matter of time before the software was made available free of charge; there are simply too many risks involved with selling this sort of thing via a standard storefront, and too many people more interested in the software's spread than profit.
It's amusing to see how much effort the industry puts into a technology that gets broken sooner or later anyway.
