Please help!! I have a Zagg InvisibleShield that I bought from BestBuy and had them install. I continually have issues with micro-bubbles (i think) over 50-75% of the screen. I've had to return it 3 times and each time I get similar results. I've waited 5-6 days, tried heating it (temporarily), and it has not cured. I have the 3G version. My wife has the wi-fi version and had a bad install the first time but it's perfectly clear on second install... Any ideas???
