I'm pretty sure this isn't a real iPhone. Call it a hunch.
Japan's News24 reports that in South Korea, three men were arrested for selling nearly 300 iPhone boxes filled with clay to a Chinese merchant for the equivalent of rough $150,000.
The clay filled boxes were sealed in plastic and weighed as much as the real deal. The group seems to have mixed in real phones, and hoped that the buyer wouldn't open all the boxes. It's the iPhone version of a briefcase full of paper with real money on the top.
Sounds like this whole deal was standing on
feet iPhones of clay.
