I emailed Power Support about a week ago regarding this issue. This was their reply :
Thank you for your interest. The iPhone 4 films will include two front skins. It is available for pre-order on our website and will ship on July 26th.
We will be offering a different film set that will include a front and back skin. The release date on that is yet to be determined. Please check Power Support USA for more information.
So yes, it will be available for front and back, but we've just got to wait for it!![]()
