Motorola's Xoom may have grabbed most of the Android 3.0 headlines of late but it's not the only tablet to run on Google's new tablet-optimized operating system. T-Mobile and LG have announced a spring release window for the newest member of the G-series of mobile devices, the G-Slate. The Tegra 2-powered device features 3D-capable, high definition display and can record stereoscopic HD video via its rear-facing cameras. Wireless connectivity is also given a speed boost thanks to T-Mobile's growing HSPA+ network.

In addition to being Wi-Fi-capable, the G-Slate will also be able to wirelessly connect to T-Mobile's HSPA+ network, which offers theoretical download speeds of up to 21Mbps and has already been rolled out to more than 100 major metropolitan areas in the U.S. It's not quite 4G as defined by the International Telecommunication Union (which has determined that the only LTE-Advanced and WirelessMAN-Advanced currently qualify as true 4G technologies) but it's still damn quick.

G-Slate users can view up to 720p high definition content on the 8.9-inch, multi-touch display but the screen is also 3D-capable. You will need to use glasses to view the 3D content on the display, although whether those will need to be active or passive has not been revealed. If you want to play 3D or HD video on a suitably large television then the device can output full 1080p HD video via an included HDMI-out port.

Wireless web conferencing and video chat is taken care of by a front-facing webcam but things get really interesting with the rear-facing cameras. These are full 1080p stereoscopic cameras that also snap 5 megapixel images and benefit from an LED flash.

The G-Slate is powered by NVIDIA's Tegra 2 dual-core mobile processor running at 1GHz and comes with 32GB of onboard storage. Finishing off the official specs are the magic threesome of ambient lighting sensor, accelerometer and gyroscope.

At the time of writing there's no mention of pricing, and folks are being asked to register to receive more information as it becomes available.
