I own one of the "surfboard" analog attachments for the Nokia 6190/5190 GSM phones. About as useless as teats on a boar hog. At $10, I think the ARN virtual PIN might be handy for a GSM customer taking off on a cross-country trip. Murphy's Law says if you break down, it will be in an area where you have no coverage. Having some backup will reduce the number of places where Murphy can work his mojo.
