Moultrie's have 2 types of firmware on them and you're right that you can view the versions on the camera itself. Write them down and you can check with Moultrie if they are the latest.
I thought the "whiteout" problem was mainly with their flash "M" model cams which they have discontinued because they never could fix them right. I hated my M60 and sent it in. Two weeks later they sent me a new I40 and the IR picks were horrible so I sold it and bought a Scoutguard. Doubt I ever buy another Moultrie.
