iPhone Box

Ok so you all know any iPhone you buy from Apple, be it a 4S through 5S, has iOS 7 pre installed right?

Well I was looking at my 4S box and it has iOS 5 icons and stuff. So I'm just wondering if I go and buy a 4S from Apple right now, will the box have the same iOS icons on it? Or will it be updated to iOS 7? Because if it had iOS 5, wouldn't that be false advertising?

i don't know, just curious

thanks in advance!
