How can you find who a cell phone number belongs to?

Answer

This must be like those unknown callers that call all the time because this person called my cell phone 3 times last night and whenever I picked up they didn't say anything. I answered all 3 times. The third time they called I continued to pick up and still nothing. So I finally got so mad that I yelled "STOP CALLING ME!" And weird enough, they stopped calling. Then a few minutes ago I searched the number on a website and found that it was coming from a cell phone in New York, New York. I thought it was from Canada. Also, I called back and it's not a valid number! I will continue my research though.
