Sprint begins accepting pre-orders for the 4G LTE-packing LG Viper tomorrow, but the phone’s official release date may have been outed early. An anonymous tipster has shared an alleged Sprint internal screenshot with Engadget that names April 22nd as the device’s planned launch date. A planned launch for the LG Viper just a week after pre-orders start sounds like a sensible game plan but, with no official word from America’s third largest wireless carrier, we’ll continue to hold our breath as we wait for this coiled Viper to strike.
