Sprint

It appears that when Dish wants something it doesn't give up.

After making a surprise bid of $25.5 billion to acquire Sprint on Monday -- which would snatch the mobile provider from the hands of Japan's SoftBank -- Dish submitted a filing to the Federal Communications Commission on Thursday claiming a SoftBank acquisition of Sprint wouldn't be good for U.S. national security.

A US Congressman has said that Sprint and its Japanese suitor Softbank have both pledged not to use equipment manufactured by China's Huawei in Sprint's wireless network, a move that could help the companies clear a hurdle in their planned merger.
