PSN Safe Way Online

hey everyone, :)

I have ps3 with ps3key and i installed a debug update to turn FAT PRINCESS to full version and i also don't have stealth Open backup manager or stealth multi-man

DO I HAVE TO DELETE THE FAT PRINCESS AND DEBUG UPDATE???

And how would I do that???

Also I heard there are logs that hold info on what games you play so is there a way to delete all the files that SONY scans when you connect to PSN????

And is there a Stealth multi-man manager or Open backup manager????
