Change your voice and number on a whim

I found a great product for the iphone it is called SpoofApp change your voice from male to female or viceversa, caller ID and phone number. Use if for good and not for evil. place a call and have it recorded too. Can calls be traced back to me?
Your financial, personal and call records are all confidential and are untraceable. However illegal activity will not be tolerated. Your phone must be unlocked, I can do this for you. try the service and tell me what you think.
