Making something legitimately yours to profit from it is the very basis of capitalism. And one way of doing that is by realising value which the original owner does not realise, so he either sells it to you at a very low price or - in the extreme case - gives it to you. If a call was made to Apple and Apple refused to take back the phone, that's what happened.That is nothing better than rationalized thievery.
Haha, funny you should say that. I have over $150 in the drawer beside me which I found a few weeks ago outside on the ground, near a bar. I did as I described: I picked up all the notes, finished what I was doing, returned home, and called the local police station, giving as much detail as possible. Details were recorded, and because no-one claimed the money after 1 month, it became legally mine. And I'd do exactly the same if I found your wallet, Sir, though if I found your details in it first and I called you up and you said you had no interest in it, it'd be mineI have no doubt you are the kind of person, who if you found a wallet would just take the money and toss it.
Mind you, if you later recalled that you had an important item in it, e.g. family trinket/photo, I'd almost certainly still give it to you. And I'd dump the cards at the nearest bank. But once you'd initially refused it, don't expect the cash value!
