Starting December 4th, customers may purchase the LG Nitro HD on AT&T for $250 on a two year contract. The LG Nitro HD represents AT&T’s latest addition to its LTE lineup of Android smartphones. Internationally, the LG Nitro HD is known as the Optimus LTE. In fact, the LG Nitro HD is going to be one of the best smartphones offered on AT&T given its powerful specs. To begin, it boasts a 4.5 inch touch screen display with an HD resolution of 1280 x 720p, 20GB of onboard memory, Android 2.3, LTE connectivity, a dual-core 1.5GHz processor, and presumably an 8MP rear facing camera and a front facing camera. Again, the LG Nitro HD will be available starting December 4th for $250 on a two year contract. Even though LG has not officially stated whether the LG Nitro HD will be upgraded to the ICS, it is likely that it is going to be upgraded in the near future.
