That would be Samsung's claim, and thus the release of other, earlier mockups from Apple which more closely resemble the eventual iPhone. And again, Samsung's claim is based on an interview with a Sony designer about a product[0] which looked nothing like an iPhone, which inspired Apple to produce one mockup merging one of their existing designs with Sony design elements. It is not based on any Sony product.
Despite what I've been saying here, I'm not an Apple partisan, but come on-- this is totally ridiculous.
