Why do you keep posting the same thing over and over in all threads? All this shows that the removal of 'Other OS' at this time makes no sense, won't stop the hacking of PS3 and it will not be needed to use any exploits once they are discovered.

lol, your the last person who should be saying something like this

But this time he's right. Once discovered, one way or the other, Linux or not, the working, not just concept, exploits won't use Linux at all to run pirated games, as games run under Sony's proprietary OS, not under Linux. BTW Linux has limited access compared to Sony OS and games, to HW and SW features, so, even if a working hack were found, to even hope to run PS3 games under Linux, some rewriting of kernel, drivers and libraries would be needed and an emulation layer should be added. How long did it take to make previous consoles acceptably working emulators?

I could be wrong here but from memory that wasn't how Geohot's hack worked. Linux (hence otherOS) was only used so that code could be run which would trick the hypervisor to run unsigned code. The concept of turning this into a method of playing pirated games was that a mod chip would be created that transferred the same bit pattern onto whatever Cell data lines that the Linux code was transferring on, just having the same effect as Geohot's convoluted hack. Once this was achieved it would be possible to get the hypervisor to do anything, such as ignoring BDROM type checks and serial ID checks whilst in the PS3 OS, thus allowing pirated games to be played. There would be no need for a PS3 OS emulator under PS3 Linux.

By killing off OtherOS support, Sony have removed the avenue for getting the hypervisor to run unsigned code using the current hack.  Geohots current plan is to find a way for older firmware versions to work with PSN, and then later to create a custom firmware that can trick PSN into thinking the PS3 has an authentic, up to date firmware version. The key issues I see that Geohot hasn't explained yet is how he plans to circumvent whatever steps the PS3 uses to confirm a firmware version is authentic. Because it seems to me that custom firmware would have been one of the first methods tried to break the PS3, the fact that no hack came out that used that supports my belief that Sony's firmware authentication procedures are very thorough. Even assuming Geohot has whatever codes the PS3 uses to confirm a firmware is authentic, by removing OtherOS support Sony have removed Geohot's access point, allowing Sony to change those codes in a newer firmware update without Geohot being able to find them out without coming up with another method of getting the hypervisor code.
