the serial # verification is to confirm that the PS3Key is legit. Obviously, if its a clone it wouldnt work with any PS3Key updates. I received my review sample yesterday and been playing with it. I have a teaser.pkg that I got and is suppose to be a teaser for PS3Key's Loader. However, using my P3Free or Teensy, the PS3Key Loader did not load. It only loaded when I had my PS3Key in the USB port.
