As expected, Amazon introduced its smartphone, called the Fire Phone, at an event in Seattle.

The phone has a 4.7-inch screen, aluminum buttons and a high-definition LCD display, among other features.
As previously reported, the phone has some 3-D functionality, which Amazon CEO Jeff Bezos called "dynamic perspective." This allows, among other things, the user to scroll through applications (like a set of phone numbers) just by tilting the phone, rather than touching the screen.
Bezos said this is accomplished by a series of front-facing cameras that track the user's perspective, in order to render the phone's interface in 3-D.
The phones are priced at $199 for 32 GB, or $299 for 64 GB, with a two-year contract with AT&T, or $650 without a contract. It's available for pre-order Wednesday, but starts shipping July 25.
