Well, there's the I Am Rich app[0], which essentially did nothing and cost US$999.99.
The crux was, however, that the developer was totally upfront about what you got for the price and apparently there still were douchebags around forking over the cash to buy "status".
Apple yanked the app due to the publicity. Which I thought was wrong. It didn't violate any App store rules and it was honest and up front in the description of the app.
