Free iPhone 6 from actual apple website: scam, or not?

So I for some reason got on the apple website (i don't know how tho) and it popped up and said something like "you have been selected to win a free iPhone 6 because you have a Samsung phone and we want to make the test trial for the iPhone 7 better!" So I answered some simple questions. And none of which were like, personal or anything. They were all like, what do you want to see in the iPhone 7? Do you currently own any apple products? Do you have a valid us address to ship your iPhone 6? And stuff like that. At the end, (there was only like 3 questions) there were people who took pictures and were like, "thought this wasn't legit. Then got it in the mail. Along with the free t shirt!" And stuff like that. I just want to know if this is for real. My mom says it isn't but I kinda think it is. She won't let me finish the survey whatever thing. Do you think it is legit?

Those sites probably have viruses and spyware

That is a scam and a way to fake you into give them personal information.
But hey if you want to try it, no one here will stop you.

But I will sprout wings at 12 noon Monday, on live NEWS, at the Space Needle and fly around it several times, before you get a free iPhone out of that "ad".

Never trust this stuff. It's basically adware the pretends to be the official site.
