ps3 ME controls

Hey polygon crew,

Just wondering if anyone can tell me if you can flip the x-axis in the ps3 versions of ME games? Aso, if you can, is the setting ignored when you use "down the sights" (im looking at you infamous). Reason I ask is I played through the whole series on PC but since i killed my windows partition am thinking of getting the trilogy on ps3. Only concern is the controls, especially since I remember relying a lot on head shots and i'm a bit rubbish with the old analogue sticks :/
