How to make iPod touch look like an iPhone 4 or 5?

I don't need a phone right now but I want an iPod touch and I prefer the look of the and feel of an iPhone 4 or 5.So this there a place where I can buy one for the price of an iPod touch.

Added (1). I don't mean a case I mean I putting the insides of an iPod touch inside an iPhone 4 or 5 because I prefer the iPhone 4 and 5 style to the other apple designs.

You can always buy someone's old iphone and just use it for music, which works nice. Or, the itouch 5 kind of fits in the iphone 5 case, the camera part is a little off and you might have to put a small thing to fill the tiny empty space but other than that it fits okay (depending on the case)

Only the feel and size.
The camera will prove that it is an i pod
There's no way it could look like an i phone 5
And btw a big cover would work it'll still prove that its an i pod.

No just buy an unlocked IPhone and use it as an ipod
