Unlocking Trophies does make a sound after all 

by Andrew Jeffery - July 1st, 2008

Looks like Sony are improving Firmware 2.40 already. Yesterday on their blog they stated that currently you will not hear a sound when you unlock a trophy. Now this has changed already and its turns out that they now will make a sound when you unlock a trophy. Speaking on the Official Blog Eric Lempel stated: " How quickly things can change - there *will* be a sound effect when you unlock a Trophy." While not a massive change, but some users will be pleased to here it.

Resistance100: maybe

CrapFactory: Maybe it wasn't a change. Maybe the guy didn't know if it did or not and guessed wrong?
