For the past 2 hours, I have had my will tested in ways unbearable to the common man. I have been trying to put a screen protector on my iPhone 5 without getting dust or bubbles or anything. Finally, it is done. I have fought with dust, lint, bubbles, moisture, oils, etc. I pulled out all the stops, steam, spray, compressed air, tape, the works. The clouds have parted and the sun is shining. It is done, and it looks great. If you are trying to accomplish such a herculean feat of strength, keep trying. If you get dust on the screen protector, take it off and run it under the sink. There is hope.
