Much to the chagrin of T-Mobile users, the fourth carrier in the U.S. to have the iPhone 4S is C Spire Wireless, a small regional carrier.
C Spire was formerly known as Cellular South and has over 1 million customers in just 4 states. T-Mobile, the smallest of the majors, has 33.6 million customers.
There was no other word on the deal except that C Spire says the phone will only be available to contract subscribers, not pay-as-you-go.
