I don't get how his buying through his company makes it any easier for me? I have his home address. I doubt the police will have any trouble finding this guy if they want to look into it. I can look at his house through Google Street View. The problem is that my feedback is meagre compared to his company's powerseller status
I have a good case and all the evidence is on my side. I'll see how the Paypal claim goes, if it starts going south I will get the police involved.
If he's a good scammer...the shipping address you sent it to probably can't be linked to him.
In the end...if this goes to a police investigation...the key to proving prior ownership of the iPhone would be the ID and serial numbers that you retained. Bottom line....sounds like should the police run this guy down it will come down to proving your original ownership of the iPhone he retained. And if you have purchased the iPhone through Apple or AT&T then you can prove original ownership of the phone.
