Forum:Armoury Unglitch - PS3

I've been trying to find a fix for my glitched armory. I managed to get all 3 quests by joining a random game, and tried to complete them all but didnt manage to get the reward for the assault quest. I've heard this can be fixed with sledge firing over the top (wwhich I've managed) and some grenade jumps. Question is does anyone know where these grenade jumps should be done? If nobody can help in that respect, is there anyone doing the quest which I could tag along to and complete it?

P.S. I've heard of the medikit glitch but this doesnt seem to work on PS3 because the items disapear too fast. If 3 other people are in a similar situation then it might be possible forus to help each othe out.
