As we previously warned, AT&T is set to officially launch its 4G LTE network in five markets today (though the service has been soft launched in certain markets for nearly a month now). If you're lucky enough to live in San Antonio, Chicago, Dallas, Houston, or Atlanta, you should be able to check out the new high speed network any moment now. Let us know in the comments what kind of LTE action you're getting into.
