I ended up updating to 4.05 and managed to get the 1.02 update installed a few weeks back. I managed to use PSProxy and SKFU Pr0xy to at least download the 1.03 update, but it appears to require either 4.06 or 4.07 and refuses to update the game without updating the firmware. Even with PSProxy on, it tells me the system software needs to be update, but if I click update now, it says I have the newest version. I'm guessing Sony will only be pushing 1.03+ directly from now on, so no more updating the game at all even from 1.0 without updating the system past 4.05.
