The device has the Apple logo and "iPhone" branding, but no FCC logos, serial number or IMEI on the rear, and appears to be in very good condition.
The handset apparently runs a much-sought-after hackable debugging OS called "SwitchBoard" and features a red lightning dock port with a serial number of C39NW00KG876. The seller claims to have bought it from a friend. The auction currently has one bidder.
In October 2014, a similar prototype iPhone 6 with red Lightning port was offered on eBay by someone claiming to have received the handset by accident. The auction garnered almost 200 bids and reached over $100,000, before being pulled by eBay, likely at Apple's request.
