Spotted on eBay, a prototype of an iPhone 6, 64 GB. Given that Apple has sold several million units, it was bound to happen. Apparently, the seller received it by mistake from Verizon. In addition to the SwitchBoard system (for testing purposes), the iPhone has no markings on the casing and a red Lightning connector. As of my writing on October 6th, it was priced at nearly €90,000.
Later, it was re-listed with a comment stating that Apple claims it is not a prototype (technically true, as it is a model with a test OS), and the company offered to exchange it for any iPhone model (including the 6 Plus).
