I would recommend any of Incipios Cases, and I show mine to any IPhone owner I come across.
This is my second Edge case - just had to get the new deep red color! Love it!! It protects my iPhone4 perfectly, and I've dropped it many times. I don't use the screen saver as I've found the iPhone4's screen far superior to the previous models. Openings for all the buttons are perfect. You simply can't beat the Incipio cases and this one is a dream.
