AT and T has taken the unusual step of publicly admitting that they can’t handle the amount of data that their smartphone (mostly iPhone) using customers are using, and have indicated that they are going to try to “educate customers about what represents a megabyte of data.” And then they are going to start penalizing “heavy users.” With so many Apple iPhone complaints about lost calls, dropped calls, and poor coverage and other iPhone problems, it’s about time that they did something, although we’re not sure that cajoling, educating, and threatening users is the right ‘something’.
