Right well i don't know what's happened here...
Took the photos on my iPhone 4S & you can see the oval in the centre of the mirror. In one photo i'm pointing to the edge of the oval bit & in the other you can see it on my white hat.
Upload the photos to the PC & you can't really see it. So maybe if you take the photos off here & put them on your iPhone it'll show?
I'll upload all the same..
