Sprint Nextel, an acquisition target of both Japan's SoftBank and Dish Network, posted a smaller than expected quarterly loss, even as it saw steep customer losses from the Nextel network it is shutting down. Sprint, the No. 3 U.S. mobile service provider, on Wednesday recorded a first-quarter loss of $643 million, or 21 cents per share, compared with a loss of $863 million, or 29 cents per share, in the year-ago quarter. Analysts had expected a loss of 33 cents per share, according to Thomson Reuters. What's Sprint stock doing now?
