One's an Apple iPhone, one is a prototype phone from a company called Meizu.
According to a report on Tom's Hardware Blog, at the CeBit trade show German police confiscated these Meizu phones and marketing materials, and are due to announce similar action against other new devices that bare an uncanny resemblance to Apple's product. Whilst Tom's blog calls the Meizu phone "blatant product piracy", whilst Engadget is more reserved, calling the iPhone Meizu's "muse".
We await news of what legal action Apple will be taking against Meizu and others.
