Collection of discolored iPhone 4 displays  (Source: Gizmodo)
Look at the stars / Look how they shine for you / And everything you do / Yeah they were all yellow

This isn't the first time we've heard of display issues with a new Apple product launch, but hopefully it will be the last. There are reports from around the web that Apple's latest “magical” device, the iPhone 4, is suffering from yellow spots on its high resolution Retina display.

In some cases, the discoloration is showing up as yellow spots in various places on the iPhone's screen. In other cases, yellow lines are seen running across the screen.

According to Mac Rumors, some customers who have taken the iPhones to Apple's Genius Bar for replacements have been told to hold off until the phone is officially launched tomorrow. Given the supply issues that Apple is currently having with the iPhone 4, getting a timely replacement likely isn't guaranteed.

If you recall, Apple had problems with yellowed displays when the current generation iMac launched earlier this year. After numerous reports flooded the net from concerned customers, Apple finally acknowledged the problem in late February.

Apple's iPhone 4 sells for $199 for the 16GB model and $299 for the 32GB model.

There are now numerous reports that there are also issues with the iPhone 4's cell signal dropping out when you hold the phone in your hand a certain way due to the external antenna. Conveniently, some people are suggesting that using Apple's colorful $30 "bumpers" solve the problem.

Here's another interesting tidbit of information regarding the yellow screens on the iPhone 4 (and possibly explains why some people are seeing the yellowness go away magically after using the phone for a while). An Apple Insider forum poster, austingaijin, stated the following:

Apple is using a bonding agent called Organofunctional Silane Z-6011 to bond the layers of glass. Apparently, Apple (or more likely Foxconn) is shipping these products so quickly that the evaporation process is not complete. However, after one or two days of use, especially with the screen on, will complete the evaporation process and the yellow "blotches" will disappear.

How do I know? I was involved in pitching Z-6011 to Apple.

So if you do have an iPhone 4 and are having problems with yellow spots on the screen, give it a few days and see if it goes away.

iPhone 4 Loses Reception When You Hold It By The Antenna Band:

This shows you that it's always best to wait for the early adopters to find those issues.

So basically you short the antenna if you hold it wrong? That's a monumental design flaw!

That also raises a lot of questions. You’re essentially putting radiation directly through your body, quite likely through the same part (if you hold the phone the same every time).

I’d be interested to see how the transmitter responds to that. Does it ramp up the power? Surely some independent testing is needed to determine if the levels are safe.

These are radio waves. The fact is the thin plastic casing of any phone does very little to reduce the output. Output is generally related to the size of the antenna. In this case it's a huge one. In an intelligent design that should make for better reception and lower power output. In a bad design power output would go up a lot.

Maybe we'll be lucky and it will stop these ibots from reproducing.
