Preproduction AT&T Nokia Lumia 1520 Makes Its Way To eBay

A preproduction unit of the Nokia Lumia 1520 for AT&T has somehow sneaked its way to eBay. The seller has listed the device for an attractive price, just $575. An unlocked 1080p quad-core Lumia phablet from team Nokia is certainly worth that price, especially for Windows Phone lovers (this device comes with WP8 GDR3 and Nokia Black out-of-the-box).

Here's a short description of the device,

This is a preproduction device. Final design hardware and software. It is just a network test device.

How about nabbing a 16 GB unlocked Lumia 1520 weeks before the official November 22nd release date?
