Summary Box: Tiny US phone co. is getting iPhone

NUMBER 4: C Spire Wireless will start selling the iPhone 4S in a few weeks, becoming the fourth wireless carrier in the U.S. to do so.

NUMBER 8: C Spire is the country’s eighth-largest phone company, so it’s a major coup. So far, only the three biggest carriers sell the iPhone in the U.S. C Spire is bypassing the rest, including T-Mobile USA and U.S. Cellular, in getting the right to sell it.

C SPIRE’S SERVICE AREA: C Spire has a million subscribers in Mississippi as well as the Memphis, Tenn., Mobile, Ala., and Pensacola, Fla. areas.
