    Your belief is correct. Jamming communications is against the law in the United State of America. There is only ONE exception to that. They may be used in medical facilities ONLY, because the reception of cell phone interference can disrupt the use of medical devices. Devices that may be keeping someone ALIVE.

    The poster ahead of me that works at verizon… I’m impressed. Why? Because I’m the merely the tech specialist at the Wal-Mart in Rohnert Park, CA. I actually sell HIS verizon phones. I just recently went to a verizon conference in napa county. You guys are releasing a great line up of phones. However, I just now lost a bit of confidence in verizon based on this verizon employee.

    Why? Because:

    In the United States, United Kingdom, Australia and many other countries, blocking cell-phone services (as well as any other electronic transmissions) is against the law. In the United States, cell-phone jamming is covered under the Communications Act of 1934, which prohibits people from "willfully or maliciously interfering with the radio communications of any station licensed or authorized" to operate. In fact, the "manufacture, importation, sale or offer for sale, including advertising, of devices designed to block or jam wireless transmissions is prohibited" as well.

    Note the verizon employee. Don’t post assumptions.

    Cellular jammers aren’t illegal. They are where people cannot use their phone. Verizon actually over goes jammers. If their is a jammer in an area Verizon will still get somewhat of a signal-enough to complete a fairly clear call and not drop it. Text messaging won’t work.
    The phones work because of their analog coverage. Cingular will not have service because of their all digital network.

    They aren’t illegal if it is posted that they aren’t allowed or won’t work.
