Apple intros a smaller dock connector and calls it Lightning, but fret not, there will be an adapter
The cable connector is reversible, with pins on both sides, so it doesn't really matter which side you plug it in if you are in a hurry, which is svelte. The reason for the move, except to save space, Apple quoted to be that much of the things that we used to do with cables, are now done wirelessly.
