AT&T has announced that the Motorola Atrix 4G smartphone will be available for preorder Feb. 13. The carrier also disclosed new information about pricing. For example, an Atrix 4G will cost $199.99 with a two-year service agreement. AT&T will also offer bundled pricing for the Atrix 4G and one of its more prominent accessories, the Motorola Laptop Dock.
