The Motorola Atrix HD was tipped a while ago to launch on AT&T, but we haven’t seen too much information regarding the high-end smartphone since that time. Earlier today, however, Motorola posted images and information on the Atrix HD, but has since removed the page. Fortunately, we know many of its specs and have a better idea on its appearance. Unfortunately, we do not know its price tag or when it will come to market, but my guess is later this Summer. In terms of specs, it features a 4.5 inch HD display with 1280 x 720 resolution, 8MP rear facing camera, 1.3MP front facing camera, 1.5GHz dual-core processor, 8GB of onboard memory, 1GB of RAM, Android 4.0, MotoBlur skin, and 4G LTE connectivity. Overall, it is definitely a high-end device with quality hardware built-in. There’s no word at this time on its battery, but if it is anything like that RAZR MAXX, then we definitely have a valuable device on our hands for AT&T. We’ll keep our eyes open on the Atrix HD, as I’m sure more information is forthcoming.
