Today Gitbrew posted on twitter that they have successfully dumped PS3's Bootloader from NAND and the NOR is next. The keys will be are specifically for your PS3 and you will have to decrypt the bootloader and metldr to obtain your version of them. It is not like before when everyone used Geohot's 3.55 keys. The Gitbrew team is paving the path for what is soon to become of the Playstation 3. Stay Tuned!
