How did Sony stop the exploit ?
Well, I´m not in for a new "when is the 3.61 CFW out" discussion, but i was just curious as to what the technical solution Sony did to cover up the mistakes they obviously made in the firmware.
Yes, I did see the FailOverflow demo when the exploit first was found, and the technical discussions on how it all was possible. And I also remember the hackers (Or at least forum trolls) saying, "We have now hacked the lowest possible level, Sony will never be able to repair this" (Or something like that..)
Well obviously the hackers were wrong, and Sony fixed it (since no games are playable after 3.60).
..So how did they do it ? (And should I be impressed?) :)
