For more than a year, there have been rumors that Amazon is working on a smartphone. The Wall Street Journal is reporting that Amazon is actually working on two. The Journal reported that Amazon is “developing a wide-ranging line-up of gadgets,” including two smartphones, one of which will have a 3D screen. Citing multiple anonymous sources, the Journal says the 3D-capable smartphone will not require special glasses and may even let users navigate just by moving their eyes. In addition to the two smartphone models, Amazon is also said to be working on a device for streaming music and a set-top box, the latter of which was also reported by Bloomberg BusinessWeek last month. Until now, Amazon’s hardware efforts have centered around its Kindle e-readers and tablets. However, CEO Jeff Bezos suggested in an interview with AllThingsD in September that Amazon was planning to expand on its hardware offerings in the coming year.
