I already did that But that wont be enough to convince them....even though the viewfinder shows "black" in such a solution, the main goal is that the camera spplication shouldnt load....

The disadvantage of the black paper solution is that, if they decide to remove the paper, the camera comes to life....
But if the camera app doesnt open and a popup message comes up, they'll digest it....as nobody even knows what 'maemo' is.....to doubt about a script or software lock...
