Just noticed this as I turned on my PS. Hopefully I can get the 4.00 upgrade for superstardust now. Will be testing shortly, so I'll let you know what new stuff I find :-) Happy upgrading (hopefully no bricks this time!!!!)

Edit: First thing I noticed was the option to shut down the system after update.

Edit 2: No noticable differences. Meh. I guess it was just to get the in game xmb feature for the ones that missed out on the 2.40 update. Oh well, still no update for super stardust. I'm not gonna play it till I can get some trophies!
