On Wednesday, Amazon is expected to reveal its long-rumored smartphone. And while details are scant, including its scheduled launch markets, the Wall Street Journal (WSJ) is reporting that AT&T will be the exclusive carrier for the device in the US. Earlier this month, Amazon announced a special launch event in Seattle on June 18 for a new device, and it’s rumored to be a smartphone with 3D capabilities. The company also released a teaser video, with customers displaying visible ‘awe’ at what they see before them. We’ll be bringing you full product details of the new Amazon device tomorrow.
