Well, I bit the bullet and upgraded both iPhone 3GS’s to iPhone4′s. Yes, I *did* do it on the Launch Day here in Australia, but not by lining up – granted, some people enjoy the experience, but I can’t think of a more useless waste of time. I like my warmth and comfort !

Especially when I called my local Telstra store and asked them to reserve two if they had any left – they did, and apart from a minor porting hassle getting one of the numbers over from Vodafone, all went well. The lovely Natalie, and the slightly less lovely Nick were brilliant.

No evidence of the signal issue yet, despite using any and every possible variation of the so-called “death grip” that I could think of.

Interesting side note: both the phones I got were made in Week 30 (as signified by the 4th and 5th digits of the serial number) – the only people I have seen having demonstrable signal problems related to grip are owners of phones made in week 27 or earlier.

Engineering change, Apple ?  Most likely…

Anyway, to the “yellowing” issue…

Nothing noticed on either phone displays, despite using in direct sunlight and examining the display in minute detail. So far, so good.

As for the picture yellowing, it DOES exist, but I don’t think it’s a hardware flaw, I believe it’s the way the white balance is set for the external camera.

Here are a couple of pictures taken outside this morning, in full sunlight (something that has been conspicuously absent in Sydney recently. See if YOU can pick the one taken by the front-facing camera. Try to base your evaluation on color saturation, yellowing (white balance) and not resolution / focus.

I should mention that the image taken with the main camera has been resized ONLY in Photoshop to be 640 x 480, the same as the front camera. No other enhancement was done.

Even knowing which is which, I’m damned if I can see any yellowing on the photos at all.

Now, let’s move to a couple of photos taken inside, with just ambient room light (halogen bulbs) this morning. In an effort to actually enhance the yellowing effect, I places my ASUS 1000HE Netbook (which is a brilliant pearl white) on an old yellow IKEA table the kids play on. Here are the results;

In the indoor shots, the effect is far more pronounced. Using the same criteria, it’s fairly easy to see which is the front and which is the back camera photo.  Again, the main camera photo was resized ONLY in Photoshop.

This is really no more than I would expect with any small CCD non-white-balance-ajustable pocket camera. My little Nikon pocket camera has the same effect.

Hopefully Apple will add a white balance compensator in future releases of the software – WITH a manual override, no less. Then corrections can be made in-camera and not in post-processing.

Overall, for the size of the CCD and the technology involved, I’d give Apple a 4.5 out of 5 for the cameras.

    Halogen bulbs have a higher colour temperature not that far from sunlight, which the cameras on the iPhone 4 are known to work well under. The yellowing issue tends to become prominent under incandescent tungsten bulbs which have a much “warmer” (i.e. lower) colour temperature.
