The 32GB LTE Version of the NVIDIA Shield tablet is almost ready to hit the streets. The company just put it up for pre-order for $399.99. That's only $100 more than the not LTE-version. The pre-order for this one will ship on September 30th.
This version is certified for AT&T's network in the US, but it is unlocked so it should work on any GSM LTE networks. It's specifically compatible with LTE Bands 2, 4, 5, 7, 17 and HSPA+ Bands 1, 2, 4, and 5 in North America, and LTE Bands 1, 3, 7, 20, and HSPA+ Bands 1, 2, 5, and 8 outside of North America.
