I purchased a PPC-6700 on eBay listed as "New, Unused" but open box. Seller had 100% feedback.
I received it today and tried to activate it. Sprint told me it cannot be activated as it was reported as lost or stolen by a business customer.
I went back to further investigate the eBay seller, and I see he bought the phone there a few weeks ago. When he bought it the auction terms stated "ESN not clear". Obviously he didn't know what that meant so he bought it and when he couldn't activate he went to resell it. However in his auction he didn't mention that the ESN was not clear.
I tried to call him but the phone number listed with eBay is not his. I've emailed him and started a PayPal resolution dispute.
