for all those wondering why it is/isn't illegal
In the US (and some other countries) it might be illegal due to the DMCA - http://en.wikipedia.org/wiki/Dmca - signed into law by Bill Clinton back in 1998 (obviously other laws don't have the DMCA, but they have their equivalent law). Thanks to the DMCA you can not bypass DRM software.
There is nothing illegal about hacking a PS3, so long as performing said hack does not bypass any DRM built in by Sony. Right now I'm not aware of geohot actually bypassing the DRM. Until that is accomplished, it is legal. The Wii hacks (for example), are illegal because they bypass DRM and allow the hackers to run pirated software.
