As far as mid-range devices are concerned, the Pantech Burst is an awesome choice.  Coming to AT&T on January 22nd for $49.99, the Burst is a 4G LTE smartphone that packs a 1.2 GHz dual-core processor, 4-inch Super AMOLED display, 5-megapixel camera with 720p HD video recording, a front-facing shooter, 1,650 mAh battery, and Android 2.3.5 with Pantech's UI. 

For the price point, you can't beat the features (especially the dual-core processor), but it goes up against some other well-spec'd mid-range smartphones like the HTC Radar 4G and Nokia Lumia 710.  Is it the best option on AT&T?  Part 2 of 2.
