After jumping the gun the other day, Motorola made the Atrix HD official today, announcing the 4.5" HD LTE device for $99 and available on July 15th at your local AT&T retailer. Like we saw in the leak, the phone has a decidedly RAZR-esque design, complete with the Kevlar back. Internally, though, this is a step away from the RAZR's internals. After singing NVIDIA and TI's praises all last year, Motorola will be humming a Qualcomm tune for a bit. Which one? We're not sure, yet. Nor do we know what this means for Motorola's Wrigley LTE baseband. We do know the phone will run Android 4.0 with the latest version of non-Blur, and come with a micro SD slot, despite its sleem physique. Rest of the specs, PR images and a comparison table are below.
