MobiTV has passed the 3 million customer mark,  saying it added the latest million customers in the last six months—it hit 2 million in February. It shows that the company is still building its business, mostly in the US I’m guessing since it closed its UK service. It’s resigned the deal it had with Sprint, where it offers Sprint (NYSE: S) TV, Sprint TV Extra and Sprint TV en Vivo. “The two companies said they have attracted “a large number of subscribers,” but did not offer specifics” reports RCR News.
