Sprint is currently a part of two major financial moves: Japan-based SoftBank recently announced its intentions to acquire 70-percent of the carrier and, yesterday, Sprint said it was purchasing an ownership stake in Clearwire (after selling off a stake last June). AT&T is the first U.S. wireless carrier to speak out against Sprint’s new business decisions.

“Softbank’s acquisition of Sprint and the control it gains over Clearwire will give one of Japan’s largest wireless companies control of significantly more U.S. wireless spectrum than any other company,” AT&T vice president Brad Burns said recently. “We expect that fact and others will be fully explored in the regulatory review process. This is one more example of a very dynamic and competitive U.S. wireless marketplace, which is an important fact for U.S. regulators to recognize.”

Sure, AT&T may still be a bit sour after U.S. regulators denied its plans to acquire T-Mobile USA from Deutsche Telekom, but it also clearly doesn’t want the number three carrier creeping up on its territory.
