InfoWorld reports that Verizon Wireless will roll out a fast cellular data service in many large U.S. cities during this summer. The service, called BroadbandAccess, is based on CDMA2000 1x EV-DO (Code Division Multiple Access Evolution-Data Only). Nationwide, Verizon now offers voice and data services on CDMA2000 1x, which delivers roughly the speed of a dial-up Internet connection.
