Hi everyone. I love the Graft Leverage case for the iPhone 5, and I think I'll be getting one for the 5S when it comes out. But I'm wondering if there's a tempered glass backplate that would work with it? I think a totally transparent back plate teamed up with this great looking case/bumper would be extremely nice. Is there such a thing as a tempered glass backplate for the iPhone 5? And if so, will it sit inside this bumper?
