The Nvidia Shield launched with a bang in July, but the high-powered Android gaming tablet only came in one connectivity flavor, Wi-Fi, though Nvidia promised an LTE version with more memory would eventually be available. On Tuesday Nvidia said it has started accepting pre-orders for that 4G Shield, and that it would begin shipping on Sept. 30.

In addition to its LTE radios, the newer version of the Shield will have 32GB of storage (compared to the 16GB of the original) and will cost $399 ($100 more than the Wi-Fi version). [company]Nvidia[/company] is offering the device through [company]AT&T[/company] for $299 — the same price as the original wi-fi version — under a two-year contract. But the full-priced version will be unlocked, working on more than 70 carriers’ LTE networks, including T-Mobile’s. While the device could technically work over Verizon’s newer LTE networks, it doesn’t support any of Verizon’s CDMA 2G or 3G networks.

The Shield is the first device to use Nvidia’s new amped-up K1 processor, and it boasts the same graphical processing capabilities as Nvidia’s PC graphics cards. The Shield can not only bring the PC gaming experience to the mobile tablet, but it can also act as a conduit for games run on an Nvidia GPU-powered PC using a Wi-Fi and now an LTE connection.

Nvidia also announced three new games available for Shield: Beach Buggy Racing, BombSquad and Broadsword.
