Nobody is going to offer you $150 MORE than what you are asking for something. And if no one here can get into the phone then him selling it for $600 is scamming the person he is sending it to. Because the person purchasing it will be assuming the phone is unlocked. I would be pretty p*ssed if I bought an iphone from someone for the same price or more than I can just buy a new one for and then it is locked and I can't do anything with it. He should have turned it in to the police. I would never buy a used iphone anyway unless it was from a family member I knew I could trust. Most people lie and sell crap that is not working correctly so they can buy a new one. Then laugh at the sucker that bought it from them.
A few years ago a girl I worked with was laughing because she sold a little radio/tape player at a yard sale to a local well know guy who was re-tard-ed. He tried it there and it didn't work. She told him it just needed batteries. She knew it did not work. She took his $5 and laughed at him as he walked away.
And no the police don't give it back to you after a certain amount of time if it is not claimed. It either sits on a shelf at the police station forever or one of them will keep it.
Wow, that is awful, to scam someone and laugh about it. Some people have no conscience. I agree that the phone should have been turned over to police. If it isn't unlocked, it's definitely a scam to sell it on ebay, when the buyer won't be able to use it. Especially for that much money. No wonder it attracted other scammers.
