Both Microsoft and AT&T stopped selling the 6-inch Lumia 1520 earlier this month, but if you really want to get your hands on this smartphone, an eBay listing is selling unlocked and refurbished units right now for $249.99.
While the Lumia 1520 may have launched in October 2013, it still has hardware specs that rival those of current smartphones, including its 1920x1080 IPS display, its 2.2 GHz Qualcomm Snapdragon 800 quad-core processor, 2GB of RAM and of course its 20MP PureView rear camera.
The eBay listing is from a retailer called QualityCellz and it indicates that it has already sold 45 units of the Lumia 1520. There's no word on how many might be left, but considering that the page has "Limited quantity available" listed, we would expect that there may not be many more to sell. Keep in mind that the Lumia 1520 accepts GSM SIM cards which means it will only work on AT&T and T-Mobile networks in the US.
