Hi all, My droid is in the 3909 batch, and so far I've had no software problems. However, there are now a few pieces of dust that have found their way under the screen, around the edges. I keep my phone in my pocket, which I make sure I clean out every day. Is this normal, or is it something that I should exchange the phone for? I'm worried that if it's happened within the first week, it will continue to get worse. Thanks!
