A MacRumors reader found the photos on his iPhone 3G, and posted them. As he said:
Not sure if this is or is not the 'norm' but I just received my brand new iPhone here in the UK and once it had been activated on iTunes I found that the home screen (the screen you can personalise with a photo) already had a photo set against it !!!!
It would appear that someone on the production line was having a bit of fun - has anyone else found this ?
Unfortunately, he used Photobucket and ran out of bandwidth. There's one really good picture of the worker above (click to enlarge) and another below (click to enlarge).
