Some business customers and other users who hoped to have the new Nokia Lumia 1020 in their hands on or before the date's upcoming release date might be out of luck.
Several websites are reporting that, shortly after the new smartphone became available for pre-orders Tuesday through exclusive U.S. carrier AT&T, some customers were greeted with an email telling them the operator was already out of stock.
"We will ship [items in your order] as soon as they are available and notify you of the shipment by email," the email read. "We will ship multiple backordered items when all items are in stock."
It's unclear how many parts of the country are affected. An online order placed Sunday using a Phoenix-area zip code indicates that the phone will ship as early as July 23. An AT&T spokesperson told Phone Arena that the backorders should go out by July 25.
The Lumia 1020 sports a 4.5-inch screen; 1.5 GHz, dual-core processor; 2 GB of RAM; and 32 GB of internal memory. It runs on Microsoft's Windows 8 platform. But most significantly, its 41MP camera could be the best in the industry; featuring the manufacturer's PureView Technology, Nokia says it's designed to produce some of the sharpest images possible by any digital camera.
The Lumia 1020 is slated to hit AT&T's store shelves on July 26, priced three times higher than previous Lumia flagship devices – $300 on contract. Europe and China will get it later this quarter.
News of a pre-order sellout raises the usual question: Is it an extremely popular device, or is this simply a case of limited supply? Nokia is in a battle for third place with BlackBerry and couple of Android manufacturers in smartphone market share, and is riding a wave of positive news with this new camera-centric device. But the FInland-based phone-maker still remains way behind Samsung and Apple. Maybe this is the next step in its evolution to make a run at its bigger rivals.
