Ok ... got my new iPhone 4 a few weeks and decided to go wit a combo of the Zagg invisible shield and the PixelSkin HD case. I put the invisible shield on the front of the phone ... perfect instillation with no bubbles whatsoever ... and then I left to dry for about 48 hours. I then tried to put the phone into the PixelSkin HD case. Immediately the edges of the invisible shield started to raise up and bubble. I took off the case, and managed to get rid of most of the bubbles. I tried to get the PixelSkin HD case back on, but no matter what I tried, I just could not get the case on without raising / bubbling the invisible shield. So now I'm going to try the invisible shield with the apple bumper. Does this work well? Is it possible to get the bumper on without raising the edges of the invisible shield? Any one using this combo, and what are general experiences with it?
