Does anyone know any legit reverse cell phone websites? They're like so you

[Amy Lee rules!]

know who owns a certain phone #? Okay, so i think my bf is cheating on me. I found a cell phone number in his cell phone and he is being very suspicious but he kind of has a way of deceiving me. But the truth doesn't lie.

So does anyone have any answers? Please. Thank you. Most of the websites google turns up don't work or either scams/spams. ENTER YER PHONE NUMBER HERE FOR THE ANSWER etc. -_-
