I've had an iPhone 3G since November, and remember when I got it seeing posts about dust getting under the glass. My iPhone didn't seem to have it, or at least I didn't notice it. However, recently, I've noticed a fair amount of dust under there, including one right in the middle of the phone that's blocking about 3 pixels or so. It's really annoying to look at. Anyway, I guess I have two questions. One, did the dust really just get under there or shift inside to be more obvious, or have was the dust always there and I never noticed it. I can't look at my phone without seeing it now. Two, will Apple exchange my phone under the warranty for this? It seems like it's a default in the product, but is it covered or do I just have to make due?
