The launch of Sprint’s first LTE handset may not be that far off. Engadget obtained an internal memo at Sprint that details the launch of the LG Viper 4G. According to the leak, the Viper 4G will land over on the Now Network April 22 for less than $100. Of course, Sprint’s LTE network is not live, and there is no word on when the carrier plans to make it available. If you purchase the Viper 4G, you may be without 4G for a few weeks months. However, remember that pre-orders for the device begin tomorrow on Sprint’s website. You can check out the leaked memo after the break.
