Two US regional carriers saw contrasting results for their LTE rolluts on Thursday. C Spire had set a goal of having LTE-based 4G on its network by the end of 2011, but in a response to FierceWireless declined to say what adjusted schedule it might have. The former Cellular South may have been counting on rules requiring LTE interoperability from AT&T devices that weren't granted with the Qualcomm spectrum handover in December.
