Ok so I posted my 32gb iphone 3gs on craigslist today and immediately got a response back wondering if I still had the iphone. And then it starts getting crazy. This buyer is telling me that she will give me my asking price ($400) plus an additional $100. All I have to do is give her my paypal email and then ship the iphone to her son in Nigeria. She says she cannot meet in person because she is leaving on a peace keeping mission to kosovo. Is this a scam? Any suggestions?
