It's now October. And registering new hardware is still fraught with problems. Sony, are you listening???? We pay a lot of money for this equipment--registering hardware should be a no-brainer.
The registration form is really only needed for the PS2. The PS3 and PSP auto register as you take them online and do a "system activation". The games for PS3 (and PSP) also auto register as soon as you log onto the PSN and play them for the first time.
