I know that you can launch NTSC version on a PAL ps3 with CFW
A friend brought it to me to show it before it was released in europe.. I dunno how he did it.. but he did it
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
