Five cities (finally) get access to AT&T’s new 4G LTE network

AT&T is officially launching its 4G LTE network in five cities today, according to the carrier. That means if you’re an AT&T subscriber living in San Antonio, Chicago, Dallas, Houston or Atlanta your mobile Internet access should be faster today. The rest of the country will have to wait jealously until AT&T expands the service to 10 more cities (70 million United States residents total) by the end of the year.
