District court's conviction of defendant for unlawful use of a communication facility in connection with a drug trafficking offense in exchange for the dismissal of a drug conspiracy charge in an indictment, and sentenced to 48 months' imprisonment, the statutory maximum is affirmed where: 1) the sentence fell within constitutional limits as it did not exceed the statutory maximum set by Congress; 2) district court's drug quantity estimate represents a reasonable view of the record and is therefore not clearly erroneous; and 3) defendant's sentence is procedurally and substantively reasonable.
