These 'inbetween' 2.5G upgrades for GSM networks include GPRS (General Packet Radio Service), HSCSD (High Speed Circuit Switched Data), and EDGE (Enhanced Data Rates for Global Evolution), and all promise speeds somewhere between today's pitiful...

About 2.8 million people make phone calls over their broadband connection, a figure that includes about 2.2 million cable customers using circuit-switched technology and about 600,000 VoIP subscribers.
Ironically the internet then starts to look like a circuit-switched system à la the old telephone network. And in phase one they would like to groom the traffic carried to increase the efficiency and the earnings per packet.
