If I buy iPhone 5 now, can I install ios7 later? - 1

DON'T TELL ME I SHOULDN'T INSTALL IOS7. I LIKE IT OKAY.

If I buy iPhone 5 now, can I install ios7 later or should I wait till I buy an iPhone that already has ios7 installed.

Added (1). I already know ios7 hasn't come out yet but I'm just asking.

You should be able to by connecting it to iTunes on your computer

You can install ios 7 when its released on any iphone 4, 4s, 5

Well i had an ipod(broken now) and i only figured out how to update it two years after i got it. I updated from 4.1.1 to 6.1.4.so i'm pretty sure you can update a new ios to an apple device wireless or with a computer
