HBO Go is an online streaming service that lets subscribers catch up on HBO’s award-winning and ass-kicking TV content? It’s about to hit smartphones and tablets early next month. Android and iOS HBO Go Apps have been teased by a new video on HBO’s YouTube channel, with promises of “instant and unlimited access” to “every episode of every season” of your favorite shows, garnished with a selection of hit movies. The apps and streaming will be free to HBO subscribers, who’ll be able to get their Sopranos nostalgia on over 3G as well as WiFi. May 2nd is the date on which the teaser video ends, though it doesn’t explicitly say that the service will be enlivened then. We’ll just have to wait and see.
