Motorola’s next flagship phone for AT&T will most certainly be the Motorola Atrix 3. It was uncovered and leaked last week, possibly being called the Atrix 3 LTE and today we’ve received some more information and an FCC filing, adding credence to the rumor.

Codenamed the Motorola Dinara we are now seeing it listed as the Motorola MB886 passing through the FCC along with those AT&T 4G LTE radios on board according to Engadget. This pretty much confirms what we already knew, and that is this phone will be headed to AT&T here eventually — probably sometime in July.

The Atrix 3 should follow right along with the previous models footsteps although it’s suggested to be rocking a 4.5 or larger 1280 x 720p HD display, and will be powered by the same 1.5 GHz dual-core Qualcomm processor as the new Galaxy S III. Just like the Galaxy Nexus, Moto’s Atrix 3 will have no capacitive buttons and do all the navigation using Android 4.0 Ice Cream Sandwich’s on-screen keys — which is something I’ve been waiting for manufactures to adopt. Sadly the FCC filing doesn’t reveal anything else so we’ll just wait to wait until it leaks in the flesh to get more details.
