I'm curious to hear from anyone that has a case that came with a plastic touchscreen protector (like the Griffin Wave or the More Eternity case), how they like it and how sensitive the screen is. When I bought my Iphone 3G, I had the apple store put a Power Support Anti-Glare Film on it and then a few weeks later I got a Griffin Wave and tried using the protector with the Anti-Glare Film on as well. I noticed that the touch sensitivity suffered a bit and also that when I called someone, the backlight would stay on as opposed to turning off automatically when I brought the phone up to my ear. I'm wondering if that's because both protectors were on at the same time or are the plastic ones just that way.... any opinions??
