What's really bad is that some of these sort of things can be done over the internet. Someone I worked with registered for this free myspace tracker and used my cell phone number. I started noticing that I was getting charged $9.99 for something on my cell bill that I had not ordered. I had my provider take it off as soon as they told me it was some ring-tone thing. Sadly, it took me a few months to realize the charge on my bill so I was out about $40.00 that I will never get back.
