The phone formerly known as Dinara just got an official debut from Motorola, and will henceforth be referred to as the Atrix HD. It's a third generation Atrix device destined for AT&T, and it will bring with it a 4.5-inch HD ColorBoost display with a 720x1280 resolution (720p), 1.5GHz dual-core processor, 1GB of RAM, and 8GB of internal storage flanked by a microSD card slot for up to 32GB of additional user-added storage.
Other feature highlights include an 8MP-rear facing camera with LED flash and autofocus, 1.3MB front-facing camera, 802.11a/b/g/n Wi-Fi, micro USB port, HDMI output, 3.5mm audio jack, 4G radio with hotspot support, and Android 4.0 (Ice Cream Sandwich).
The Atrix HD looks somewhat similar to Motorola's newest Droid RAZR phones, complete with a thin profile and Kelar back; it measures 69.9mm by 133.5mm by 8.4mm and weighs 140g. Unlike the RAZR line, however, Motorola seems to be pushing the Atrix HD, in part, as a business-class device with "government grade encryption" and VPN support.
Motorola didn't say when the Atrix HD will launch or how much it will cost. At least part of that information may be hinted on the homescreen, which displays July 26 as the date.
