AT&T Wireless was officially purchased by Cingular in October 2004 and quickly absorbed. The remaining separate elements within Cingular are referred to as "Cingular Blue". AT&T Wireless was originally spun off from AT&T in mid-2001, and despite the name, operated as a separate company until the Cingular merger. The company has significant analog networks, and digital TDMA networks. They also rolled out a new nationwide GSM/GPRS network over their existing TDMA network. The GSM/GPRS network was upgraded to EDGE in late 2003, providing high-speed data service. The company also deployed WCDMA (UMTS) 3G in six cities.
