Well, lookie here. It didn't take long for Motorola's latest Atrix variant to go from unveiled to launched, as the Atrix HD is now on sale at AT&T for a wallet-pleasing $99.99 on contract. Sign the dotted line for two years, and you'll be getting a 4.5-inch Android superphone, complete with Ice Cream Sandwich (Android 4.0), a true 720p display, Kevlar-infused backing, a "splash resistant" casing and an LTE radio. Those who indulge quickly are set to grab a gratis Vehicle Dock for "a limited time," and you'll also enjoy the first Moto handset to bring the outfit's Circle Widget to the homescreen -- which is engineered to take owners directly to their AT&T account info, displaying data usage, battery status and more. The phone's listed right now in AT&T's smartphone section in Titanium and Modern White, but the link to buy it seems deactivated for the moment. Still, it's all square to go on sale today, so keep a close eye on the source link if you're dead-set on an upgrade.
