File a dispute with ebay and get a refund asap. Seems the terms of the sale have change since he has not shipped by advertised date. He doesn't have it in stock and is buying time to get its. How much did you pay?
Thankfully I won't have to do this. As mentioned in my post above. The Verizon iPhone 6 arrived yesterday and was factory sealed as listed in the description. It's been working great with my AT&T service so far.
