Version: 1.0.1

Function:
this script takes the selected objects and transforms the locked normals
into Hard or Soft edges.
Usually when the user import an object in format fbx, from other 3d package 
maya bring that object with locked normals not with hard and soft edges.

To install it you need to copy the script : "lockNormals_toHS.py"
 in maya user scripts directory:
"c:\Users\_your user name_\Documents\maya\2012-x64\scripts\"

and use these python command to run it:

import lockNormals_toHS as lockNormals_toHS
reload(lockNormals_toHS)

If you want to have it on your shelf just create a shelf button with the above comments.

Use and/or modify at your own risk.

Update:
Simplified the second step, now the script is 2 times faster
