Thanks for the support! A flat headed screwdriver fits in easily because there are 6 narrow 'slots' (two on top, two on each side), and it seems to go in behind the translucent acrylic frame and the grey plastic 'backing' (both of which have to come off intact and probably together looking at the photos on blogspot). When I apply leverage however it just forces the entire thing, bending either the frame or the case unpleasantly. There are no signs of anything becoming 'unclipped'. Perhaps its firmly adhered to the glass surface of the screen.
