Essentially this is what happened, every PS3 can read the firmware and decrypt it with the public key to install it. Hackers gained access to the public key when they hacked the system. Thats ok though because the public key is meant to be out in the open and therefore it's vulnerability is accounted for. With the public key the hackers could take Sony's firmware apart and decrypt it and study it but they couldn't put it back together and create custom firmware. What Geohot did was find the private key of Sony. Now hackers can take PS3 firmware apart, modify it and then resign it as if they were Sony to be accepted by any PS3.

Well explained... and I'm guessing that means a whole lot of problems.... i.e. there is no way to stop this without rendering every PS3 sold thus far unusable?

As far as I can tell, after reading through the tech thread on B3D.com I say theres no real practical way thats obvious on the outside. So yes there probably isn't anything Sony can do about it. The best they can possibly do is a new hardware revision, however if its coming it'd probably be another year away at best.
