Additionally, a video showing a 3.50 to 3.41 PlayStation 3 downgrade in what is being called the world's first PS3 downgrader (excluding Infectus, of course) is available courtesy of Disjod below stating that the software which appears to utilize the PS3 Factory/Service Mode requires an original PS JailBreak mod-chip.
To quote: "PS Downgrade is not a new chip, but it is the much anticipated software update to the original PSJailbreak chip. The update will be available for customers who have a valid serial, of the original PSJailbreak chip.

Well, all this talk about a downgrade option but seriously Why? It make no sense to me right now. The only thing we need is a CFW for 3.5 to play upcoming games. Even if we find debug patches wich work for i.e. GT5 , or any different moddind methods to get a 3.5 game to work... It make no sense again to do that over and over, also guess that sony will do something against those methods.
So all we need is a CFW, and i know some guys are on the best way to do it and all we have to do is be patient.
