If it wasn’t enough that the new iPhone was going to have 3G, a sleek black exterior, and a built in GPS system, there is something else to add to the list of terrific features that the new iPhone will boast. The updated version of the iPhone will have an earpiece that will be compatible with the cell phone. It will be able to be charged together with the iPhone in the same charging dock, and there will be two bars on the iPhone screen that will indicate what is left of the batteries both on the earpiece and on the phone itself.
