A leaked document obtained by Android Central indicates that the Motorola Atrix 4G dual-core gigahertz Android smartphone may be landing on U.S. carrier AT&T on March 1. Motorola had boasted that the phone is one of the most powerful smartphones on the market at its CES debut.
The Atrix 4G also has accessories that complement and augment the phone’s features, such as the Laptop Dock and the Home Dock. When attached to the Laptop Dock, which is essentially a notebook without the internal components, the phone can drive the UI with complete with multi-windows and multi-tab web browsers.
Pricing information for the phone and its accessories are still not known at this time. Android Central notes that AT&T has historically launched phones on a Sunday, and March 1st is a Tuesday, which may provide for an unlikely, though still possible, launch date.
This would be cooler if AT&T had a 4G network for it to work on.
