THX to evilsperm!!! i finally got it worked by using his method!!!! with "posadis" I am in UK and the console is us ver. As for the New RR i put US and JAP:
fus01.ps3.update.playstation.net
dus01.ps3.update.playstation.net
fjp01.ps3.update.playstation.net
djp01.ps3.update.playstation.net
N.B!! just to help the others if they are still confused. When you config the PS3 internet connection, just do anything automatically EXCEPT for when it asks you for the PRIMARY DNS. For this you have to configure manually, and to put the "IP ADDRESS" of your computer for it, I repeat the "IP ADDRESS" OF YOUR PC. NOT THE USUAL PRIMARY DNS SERVER NUMBER!!!
Well i hope this helps.
