XiStera is currently made to work with the naked iPhone 5. We have had significant interest in a case version so our design team is looking at it.
XiStera is currently funded for the iPhone 5. If this project get to a certain level it's possible we will add a stretch goal for the iPhone 4/4S. It will double the cost of the project but we love the 4/4S.
NO. XiStera will be over molded with a shiny and rigid hard rubber call TPV. Metal will never touch your iPhone and the TPV material could never scratch your glass or casing.
