A 4" display would be a pretty big deal. As would 3D support.

How about a display on the back? That way there would be (nearly) no wrong way to hold your phone.

You can only see one side at a time.

Unless you could unfold the phone.

But then it would have again a front and back... Unless... You don't mean they would add another two display on the inside back fold!? My god, quadruple displays!

I don't get why you'r downvoted. Here's my perfect iPhone: Retina display in the front, eInk in the back. As a bonus you can use eInk to 'skin' your iphone with your favorite art.
