Finally posted up my ad on craiglist to sell my iPhone 4S 16gb White. Most of the buyers seemed to be professional buyers who intend on shipping them to another country. For some reason I feel more comfortable selling it someone who plans on using the phone since I'm not really aware on how buying my iPhone $650 can be really profitable to them. So can someone aware me on how these buyers are making a profit? Also how does one get around making sure the money is not counterfeit? Would it be too much to ask the person to pull out the money out of a bank or ATM?
