The most shameless product placement ever?

My daughter just finished reading a book. She was put off by the trailer for the movie made after it, though. In the book (a fantasy), the protagonists meet Medusa and one of them – a boy – looks at her reflection in a crystal ball in order to avoid whatever happens to anyone who looks Medusa in the eye. In the movie version, the young hero watches the reflection of Medusa flicker on the shining back of his – yes, Iphone. I was going to say: This is probably the shameless product placement ever. But the race there is real tight – with all those TV episodes stitched around a product and who knows what.
