I am an European and just arrived in NYC. So I bought a nice Verizon iPhone 6 off Ebay. It was a nice sealed brand new one. So everything looks good. I am in the US right now, and trying to activate this new iPhone 6, but it says ''unauthourized device'', which probally means I need a contract with Verizon which I dont have. Is there a way to activate this iPhone here in NYC so I can start using the iPhone? thanks for your time!
