Interesting - The 4.7SE software is normally a flash update of the 900264 and 900440 versions of the CAM. Unless it has been mis-labelled it would seem as though someone knows how to flash the 901633 version and that it is compatible with the earlier versions. If you could find out the history of the CAM and how it was updated, you could probably update it to Freecam in the same way. Does it show any signs of having been opened? What else does it say on the label? Mine says "901633 Rev 1.1 F/W 0.07B".
