Cingular, AT&T Wireless and Triton PCS have reached a definitive deal under which some North Carolina coverage areas would end up in the hands of Triton.

The agreement is contingent upon approval of Cingular’s takeover bid for AT&T Wireless. The firms reached a non-binding agreement in July.

Under the deal, Cingular receives Triton licenses, network assets and customers in Virginia. Triton gets $175 million in cash plus some North Carolina facilities, licenses and customers.
