What appears to be an iPhone 6 prototype popped up yesterday on eBay, and the current bid has already reached $7,100. [See updates below.] The seller, who describes the phone as “vintage,” said they bought it from a friend. It appears to be missing an FCC logo, serial number, and IMEI number:

The seller added:

From what I know it runs a debugging OS called SwitchBoard and features a red lightning dock port with a serial number of C39NW00KG876.

According to 9to5Mac, SwitchBoard, a type of internal Apple software, is much easier to hack than stock iOS, and devices with it installed “fetch insanely high prices.”

Indeed, there’s a good chance this one will go higher: In 2014, another alleged prototype was on the market for $86,000. However, it turns out that it wasn’t a real prototype—just an unfinished phone. It was later sold for $11,000.

Similarly, this latest prototype may not even be a prototype at all, although Apple will want probably to sniff around anyway. But hey, if you have the cash on hand, why not? Just don’t leave it in a bar.
