Released on PS3 Custom Firmware
A few days ago in a previous article we discussed the issue by Geohot and fail0verflow team of " PS3 Root Key METLDR ", ie the key used by Sony to" sign "the various software. It was not difficult to imagine further developments, which arrived on time. 
In the video posted by Geohot can be seen working on custom firmware developed by him, which allows execution of homebrew does not "signed" (homemade software) on the console Sony PS3 . Everything you need has been unexpectedly released directly to their site. To perform the jailbreak just download the Jailbreak . zip, extract it and copy its contents in a pendrive. Attention to the directory structure on the pendrive, the file must have the following path PS3UPDAT.PUP / PS3/UPDATE/PS3UPDAT.PUP respecting the use of capital letters as the system is case sensitive. At this point you can just connect the pendrive to the PS3 and run the update from the "System" -> "System Upgrade". For those who previously has usatoi the custom firmware of KaKaRoTo, you should first upgrade the console firmware to the original 3:55 and then install the custom firmware of Geohot. This custom firmware will enable the launch of future Homebrew, existing ones are not compatible. We just have to wait for further developments and the response from Sony, which certainly will not wait. Here are the links to download the sial custom firmware homebrew that Geohot used in his video:
