Someone said it would be using Liquidmetal. Could this be mistaken for ceramic, which I keep hearing it will be made of?
LiquidMetal is a commercial name for a particular type of amorphous alloy.
In 2010, Apple bought a perpetual worldwide exclusive license to use
LiquidMetal in consumer electronics devices.
So, although Samsung used to use
LiquidMetal in some of its phone bezels for scratch resistance before then, Apple has made sure no phone maker can use it any more. At least, not "
LiquidMetal" (tm)"

A radio transparent ceramic back makes far more sense from an internal antenna point of view, anyway, so I think that's what Samsung might use.
Also because of that need, I can't visualize Apple using LiquidMetal for anything more than trim around the iPhone. OTOH, Apple likes form over function, so who knows.
