C Spire Wireless, the regional carrier originally known as Cellular South, has started to sell the 16GB, 32GB and 64GB iPhone 4S for $150, $250 and $350, respectively. Those are pretty solid price points for anyone within C Spire Wireless’ coverage area looking to switch to the carrier. Does this also mean the iPhone 5 is soon headed to store shelves? It’s too early to tell, of course, and we’re guessing it’s more of an attempt by C Spire to pick up a few additional contract customers. The iPhone 4S initially launched on C Spire Wireless in November of last year and, like Sprint, the company promises unlimited data with the device.
