Amazon.com chief executive officer Jeff Bezos unveiled a "Fire" smartphone on Wednesday that comes equipped with a 3D-capable screen, a feature intended to differentiate the latest entrant to the crowded mobile device market.
 
The phone also offers free, unlimited photo storage.

Bezos, in a rare media appearance, touted features that Amazon hopes might help the 4.7-inch device stand out from the pack, including an option that helps users easily buy products and TV shows that the phone recognizes.  - Reuters
