Motorola has officially announced the Atrix 2 for AT&T is launching on October 16th for $99 on a two-year contract. The phone is identical to what we already showed you in our Atrix 2 preview, including the 1GHz dual-core processor (likely a TI OMAP 4), 4.3-inch qHD display, 1GB of RAM, and an 8-megapixel camera with 1080p video capture that Motorola claims has "shutter speeds faster than a digital camera." The Atrix 2 runs on AT&T's HSPA+ network and is capable of download speeds of up to 21Mbps, so naturally AT&T is calling this a 4G device — a claim we'll be taking a close look at once we get our hands on the device.

The Atrix 2 also sports Motorola's "webdock" technology and compatibility with the Lapdock 100 accessory, but the port arrangement implies that it won't be compatible with the original Lapdock. Fans of the original Atrix's fingerprint scanner should note that it's no longer here, but the Atrix 2 does add enterprise features like microSD card encryption, VPN, and remote-wipe capabilities. Finally, there's also HDMI-out on board, including a mirror mode for displaying 1080p content on your TV.

The Atrix 2 headlines a grand total of five phones that AT&T has just announced, including the Samsung Glide and DoubleTime, the Pantech Pocket, and the AT&T Avail by ZTE.
