AT&T's Leap Wireless acquisition has reportedly been approved by the FCC.

In a last minute attempt to save its planned acquisition of T-Mobile, AT&T is turning to a little-known U.S. carrier for assistance. The No. 2 U.S. carrier is in talks with Leap Wireless to sell it some of T-Mobile’s business, hoping the move will convince the Federal Communications Commission (FCC) to approve the AT&T-T-Mobile deal, according to The New York Times.
