I've noticed that my iPhone 3GS (16GB white) has very thin cracks near the speaker grill, as well as the SIM card slot. I've searched and noticed this is actually a common problem. The cracks are very thin, so do you think this is something worth worrying about? If it gets more serious, then I'll definitely have Apple trade it for a new one. Thoughts? Edit: Nevermind, I've decided to keep this particular model. After reading numerous replies about this issue, my iPhone apparently doesn't have it as bad as others. It's only located in two small spots and it's barely noticeable, unless inspected. If it gets worse, then I will handle it. For now though, I'm going to have to buy myself a nice case.
