So with these new "leaked" iphone photos...

Did anyone else notice the volume buttons (plus/minus) are off on the 5th to last shot in this gallery here

When the iphone is laying flat down across the face, the minus button seems "upside down?" as in...a line going up and down as opposed to left to right? It's only in that shot. The rest have a normal minus line etched horizontally. What do you suppose that means? More than one casing? Or not finalized? Or fake?

hmmmmm
