Which means (to me) that ALL 3G phones will be or are Yellow? Yet I don't see everyone complaining. Is this because some haven't noticed or are there a shit load of folks who are color blind?

From the pictures I've seen, the difference doesn't look too severe anyway. And given better image quality overall, I'd say it's definitely a fair trade-off.

We see a HUGE range of "whites" in the world--even just on device screens. It doesn't surprise me at all that some people notice, while others don't--or notice but don't care.

I would think the people who would be MOST likely to notice would be those going from an old iPhone to a new one: they're used to a slight blue bias, and now a slight yellow bias seems extra yellow to them in comparison.

Most don't notice because they have nothing to compare it to.

The people who do compare it think that something is wrong because the 1st generation MUST BE RIGHT!!

No, it's because most people are relieved. Macs have traditionally followed the TV manufacturers in pursuing brightness at any cost by using ridiculously hot color temperatures: 8,000, 10,000, even 12,000 Kelvins (when sunlight is about 6,500.) Remember that brightness goes up with the fourth power of the temperature and you'll see why. Turn on your TV in a darkened room and then turn your back on it and you'll see that everything is actually some shade of blue, even though your visual cortex will (sort of) compensate for it. Every computer monitor (and TV) has to be calibrated to bring down the color temperature to some reasonable level. I know when I boot up my Mac, that first opening screen before my calibration takes over, seems just as hot and blue as a welding arc. If the iPhone can not in fact be color-calibrated, then this is a great step in making it more usable. Try watching a video before you decide you don't like it. I'll bet you'll find that it looks much more natural. But some people are so used to that blue actinic glare from their uncalibrated displays that they ARE complaining about it.

P.S.: A good test for any display is if you can't get natural skin tones without making blonde hair look green. That means the color temperature is too high, like every TV that's left the factory for the last 50 years!

i notice the difference, but that's all it is to my eyes. although i won't describe it as yellow, but a biased towards warm hues. i find the overall colors on a warm and saturated side. i find these quite pleasing to my eyes. however, i won't rely on its display for accurate colors, and of course, this iPhone model wasn't intended for rendering colors accurately.

I was in AT&T store yesterday and held my old iPhone up against one of the new 3Gs. I noticed that is was "less blue" more than I would say "more yellow". I did feel the 3G screen was brigher and of higher contrast. (However, my phone was on AUTO BRIGHT and who knows what the demo phone was set to)

Overall, I loved the display on the new phone.

I haven't really noticed a yellow tint, I did however think that the new iPhone display is much crisper and brighter. I like it :]

I wonder if we can expect a calibration, perhaps just a couple presets, under the Brightness tab (though they'd have to rename it) in a future update.

If not, I'm sure there will be such an app for Jailbroken iPhones.

Of course it was just the color temperature! Why did people think this was a "defect"?? Because Apple doesn't provide easily accessible display controls? I'm not familiar with small embedded LCD screens, but I would assume Mobile OSX controls all the hue/color temperature/contrast settings. Shouldn't it be easy to modify these settings in the hacked firmware? Anyone heard of people changing these settings?
