Can I keep an iPhone 5 that's been sent to me on accident with no records?

I made a call to a phone company for an iPhone 5 but then called back ten minutes later to cancel bacause I decided not to be on a plan but have received an iphone 5 anyway, so i called the phone company and said i had cancelled that order and they said it was cancelled they have no record of anything being sent to me. So my question is can i keep the phone and put a different sim in it.without them knowing?

HTC One or iPhone 5? Which one is the best smartphone?

I mean, between the two. Please don't suggest the GS4 since I have it already, but because of its problems, I had to sell it off. Which one among the two will last longer? I need to get a phone this week, so don't ask me to wait for the iPhone 5S. I like Android because it is an open source, and iPhone because its really smooth.

Good multiplatform (android/iPhone) multiplayer games?

I play Wordfeud with a friend of mine on my android and his iPhone. I'm looking for more two player games. We need to be able to take our turns any time because we're both too busy to play at the same time.

I already know about chess, scrabble, and draw something.

What are some other games we might enjoy?

I would really love to find a complicated strategy (Risk) or card battle (Magic) type game.

My phone is getting slow so I can't play any real-time action games or fast paced shooters.

My iPhone 4 suddenly shuts off?

It won't turn on. When I plug it on computer or charge it directly, the apple logo keeps appearing on and off but it won't turn on. It happens already before, i reset it and deleted everything on my phone and after a couple of weeks it shuts off again. When I plug my rechargeable backup battery, it would open but for only a couple of minutes and would shut off again when I unplug it. I don't want to go to apple store if possible, so is there anyone who could help me?
