iphone overheating where sim is

So my phone loses signal just by holding it at the top with fingertips I called to talk to Apple support but the guy was so rude I had to hang up in disgust. Now my phone is getting "burning" hot where the sims card is. I have never removed it so this makes me wonder. A few days ago it said no sim and I restart problem fixed. I am currently doing a restore as a last ditch effort because I was in a call for 10 minutes when my phone started to burn and then read no sim. I let it sit nothing. Eventually I pulled the sim card out and noticed a finger print and rubbed it down with a lint-free cloth put it back in and got 10 more minutes befoe it overheated and said no sim card again. I really hope Apple isn't going to leave me with a flakey device. Less than a week in I think this should qualify for some sort of lemon policy.
