I have a black iPhone 3G. While I do love the phone, the build quality leaves a lot to be desired. Everyone knows about the cracks, the light leaks, silent switch falling off, among other issues. The original iPhone was a lot better, but too bad aluminum doesn't play well with radio signals. Now we know the iPhone 3G S looks exactly the same, so I'm wondering if Apple addressed the build quality problems. Anyone else concerned about this?
