Why doesn't the aluminum cover all of the back?

    What is the point of the two tone glass and metal back? What is the issue with having the entire back completely metal?

    Radio waves don't penetrate aluminum well. So some of the several antennas in the phone are located beneath those ceramic plates.

    Yep, same reason LTE iPads has the black plastic strip on top and MacBooks have plastic covering the hinge

    Because Apple wanted there to be a little of the back that's not all scratched up.

    Something about signal issues if it were to have a full-metal back.

    Just a fine point: the 3G models have had that plastic window since the first-gen iPad. It's not just an LTE thing, it's a RF thing.
