Long story short. Bought an iPhone off craigslist. Came home, put my SIM in and everything worked. Kinda surprised when I saw the phone contact list was not erased before it was sold to me. It had tons of contacts. Found out music, photo, video - none of them were erased. The phone was not reset to factory settings. Felt the phone could be a stolen one. It has warranty for 5 more months. Apple store ID in the phone had a valid email address. Did little sleuthing. Searched Facebook for the email linked to the Apple store ID. Found the FB account linked to that email. The person's profile/wall/friends everything was open. Browsed through his posts. There it was. In June, the person complained about someone stealing his iphone and asking them to return the phone. He said he had all his contacts in his phone and he didn't have a backup. He talked about it for 2 more weeks and said he bought another phone but lost all his contacts. I am trying to call the person who sold the phone to me but unable to reach his cell. Now I am torn whether I should contact the original owner who lives 60 miles away and let him know I bought his phone from a stranger or just keep quiet. I know I cannot keep quiet, so I will contact the owner for sure and do what? He is going to get his contacts back and get his phone back too, which means I lost my money? Will he agree to split the cost? He is a student, can't expect him to share the cost. I cannot use a stolen phone. Donate it to a charity? I am using my old phone (not an iphone) now.
