Can't believe I'm asking this but does anyone know how you grab things on PS3? I try using the same way I did in Fallout 3/NV but I just switch to third person. Any help?

Hold down the action (x?) button

Yeah, on PC the action button is E and by holding that you can carry stuff around, tap it again to drop the item. And since the interface is the same everywhere, just do that with whatever your action button is.

I am on PS3 also. Just hold down the X button for a bit longer (instead of tapping it to pick an item up). Then you can move it and tap X to drop it again.
