And while it still does not have an official release date, Sprint has released a promo video that should help to hold over interested consumers until the companies can make an official announcement. The video is extremely well done and takes viewers on a tour through the previous EVO releases.Advertisement Back in 2012, Sprint launched the first EVO smartphone, the HTC EVO 4G, to great fanfare and to great sales as well.
