4G LTE is finally coming to AT&T!  Aaron unboxes the HTC Vivid, one of the two LTE devices launching on AT&T on November 6th.  It offers a 1.2 GHz dual-core Snapdragon CPU, 4.5-inch qHD display, 8-megapixel camera with 1080p HD video recording, a front-facing camera, 1,620 mAh battery, and Android 2.3.4 with HTC Sense 3.0.  It'll set you back $199.99 with a two-year contract; not bad, considering the $299.99 price point that most of Verizon's LTE phones are at.  Can it compete with Verizon's offering?
