Not a whole lot to say about the LG Viper from our brief time with it at Sprint's little get-together at the Tao nightclub in Las Vegas. You're looking at a mid-level device with a stock Gingerbread UI, LTE data and Sprint ID thrown in for good measure. It's got one of LG's excellent Nova displays though, so that's a pretty big point in its favor.
We'll get more quality time in with the Viper when we're done bouncing our heads to the beat here at Tao. In the meantime, enjoy.
