CDMA'd iPhone 4, AT&T has come clean with what's next on America's largest GSM network. While announced at CES 2011, pricing and release information had eluded the luscious Atrix 4G... until now, that is. AT&T will begin pre-sales for the Froyo-powered Motorola Atrix 4G Android superphone on February 13th, with the standard $199.99 + two-year contract ($50 more than we were led to believe, mind you) getting one into your grubby mitts. We're told to expect general availability on March 6th "or earlier," putting it just about in line with the date we'd heard rumored. Moreover, those looking to buy will should have a difficult time laying off of the Laptop Dock bundle, which nets you an Atrix 4G as well as a $499.99 dock for the grand total of $499.99 on contract. You heard right -- those who opt to buy the dock at a later time will be asked to shell out five Benjamins, whereas that same tally on day one will also include the phone. It should be noted, however, that the bundle only applies if you also sign your name to a Data Pro plan and tethering add-on, so be sure you're down for that monthly hit before committing in haste. Oh, and just in case you simply can't stop spending, the carrier is also offering an Entertainment Access Kit for Atrix 4G customers which includes the Motorola HD Multimedia Dock, a Bluetooth keyboard and mouse, and a remote control for $189.99.
