I was just at my AT&T store and I got to play with an iPhone 3G S. Although it is really, really fast, I noticed that the LCD screen has the same scanline issue as the iPhone 3G. I don't think they changed the LCD at all. It kinda makes me sad because I was hoping they'd make the screen smooth and not show those stupid horizontal lines. Here's how to spot if your iPhone has the scanlines. Hold the iPhone as still as possible and look at the light blue title bar in Mail or Messages and notice that everything is smooth. Then move the iPhone up and down a little... as you move it, the screen shows these weird horizontal lines. They only seem to show up when the iPhone is moving. I think it has something to do with the refresh rate of the display. Anyways.. my current iPhone 3G is 95% free of this problem (there's a little bit on the lower left side, but I can ignore that) so I'm sad to say... I probably won't be upgrading to the iPhone 3G S (unless I am able to take the LCD out of my iPhone 3G and put it in the iPhone 3G S, but I don't know how similar the internals are yet). How sad. Why doesn't anyone else notice these lines? When you look at your computer display, do you notice lines appearing if you move your head slightly? No you don't... why should it be on your iPhone? One more thing: I've also noticed this effect on GPS units and other small LCD screens in credit card scanners and stuff at stores... so it's not just the iPhone. Let me conclude by saying that my current iPhone barely has this problem and my iPod touch barely has a problem but, the iPhone 3G S is a lot worse and so are a lot of iPhone 3G's that I've seen in the past. It's a gamble whether you'll get a good one or a bad one. Who's with me?
