Choice is always good, and as AT&T works to build out their 4G LTE network, we're seeing more and more LTE smartphones land on the carrier. The third LTE device is the LG Nitro HD, and it's available now for $249.99. Nitro HD sports a 1.5 GHz dual-core processor, 4.5-inch IPS true HD (720p) display, 8-megapixel camera with 1080p HD video recording, a front-facing camera, 1,830 mAh battery, and Android 2.3.5 with LG's custom Android skin. It's available now for $249.99 with a new agreement. Is this the best AT&T's got in the LTE department, or would the Samsung Galaxy S II Skyrocket or HTC Vivid serve you better? Part 2 of 2.
