Typically the "free ringtones/games/apps" advertisements will clearly show the reccuring charge at the bottom of the page, something like "by entering your wireless number you are agreeing to a monthly subscription of $xx.xx" most people never notice it until they've been billed at least once if not several times. It's underhanded but legal because the person has to enter account specific information to get the "free" stuff. Some carriers do have contact info for the venders. Be sure to pass the warning on to family and friends.
