Is Apple going to (or have they already announced) change the design? Or will this be the same model for the next year? They sacrificed thickness to put the antenna in the bottom left (it was in the middle back portion on the 3GS), so I don't see where else they can fit in the phone; they either make it just a little more thick and put it in the middle back or put the antenna in a part of the phone no one would hold (like the top right). Thoughts?
