I cracked my 3G screen last week. It was my first time dropping since buying it on day one. I had it in my lap (which i normally never do) while driving and it fell flat on its face when i was getting out. I've already ordered a replacement glass and digitizer since the phone still works perfectly. My problem is that I can now see dust specks accumulating under the glass. What's the safest way to clean the LCD when I'm taking it apart? Oh, here's a pic of the damage.
