iphone5 holder for iphone4 stands

I was searching long time for an usfull adapter for iphone 5 which i can use for every holder out there on the market.
But all out there don't work well. So i desidet to do one on my own.

This one is my first version. It work with every standard iphone 4 stand. So you don't have do buy a new one. And it works with most car holders. I used it for my vw passat.
