How to disable hints in Uncharted 2

The game disables certain "game altering" cheats (like one-shot kills, unlimited ammo) on difficulties you haven't finished the game on already, if it allows you to change costume, it shouldn't lock trophies or your ability to unlock Crushing

At least in the US, my copy of Uncharted 2 in the twin pack is the GOTY edition, and came with a PSN voucher code for all the bonus content. I can't be sure this is the case with an Australian copy, but it doubly doesn't make sense for there to be a GOTY edition they're not giving you AND for there to be a version difference this significant between the regions.
