Probably it was the last week when Sony proclaimed that they are taking away the Install Other OS option from the PS3, where as the latest roll out i.e Sony Playstation 3 Slim proves as you wont find Install Other OS option there, on that point followed desecrate, and now, a hack on.
However a famous hackster George “Geohot” Hotz proves that he can run the latest firmware (3.21) or PS3 slim with other OS. However if you have upgraded your console’s firmware and obviously you wont be getting this option, there is no solution to degrade it back. Watch out the hacked video here.
“Hotz writes: “This can be installed without having to open up your PS3, just by restoring a custom generated [PlayStation 3 Update File] file, but only from 3.15 or previous. It’s possible this [custom firmware] will also work on the slim to actually *enable* OtherOS.” The redesigned PlayStation 3 slim model shipped without the option to install another operating system.”
