Apparently Sony has made an official 3.50 / 3.51 ISO loader in their new firmwares. The file is called "np9660.prx" and many are speculating that this is the first step in what Sony has promised us a long time ago – a virtual downloading resource specifically for the psp. Is Sony going to be selling commercial games via this service? Perhaps time will tell. All we know at this time is that the psp is ready for such developments in the future, so let's hope Sony gets their minds set straight and get this service up and running already.
