    Dammit! Just noticed I've got a dead pixel on the right handside about a third of the way up. Can you claim a replacement from Apple for just one dead pixel?

    I would take it back. A dead pixel is a defect of the screen and a $650/750 touch screen product should not have defects.

    I thought the minimum had to be 3 before they replace it? Whats the best way to check for dead pixels?

    If they'll replace it for my wonky SIM tray they should replace it for a dead pixel.

    The threshold for an iPhone is 1 pixel. The larger the screen the more pixel anomaly threshold. As long as it's under warranty, they'll replace it.

    Give it a try. I had a small black spot below my screen. Not sure whether it was a dead pixel or some other thing.

    Anyway I brought it to my Telco (in Singapore it's the telephone company that has to service the iPhone), the guy looked at it and brought out a replacement for me 2 minutes later. :)

    To test for pixel anomaly would depend on what kind of anomaly you have. If it's a bright pixel (stuck on) then resetting your iPhone to the apple logo would be your best bet to test because it's a black background. If you have a dark anomaly (dead pixel) then opening a new page in Safari would give you a blank white background. With the iPhone 4, you may need a magnifying glass to see the individual pixels.

    noticed a dead pixel in center while watching a music video with lots of white. Knowing that the answer is subjective, what is an acceptable amount of dead pixel(s) for ya'll to warrant an exchange?

    Thanks

    I had a dead pixel in the very top right corner and they exchanged it. With that being said, the replacement had 3 dead pixels, they swapped it again with the genius mentioning that there is such thing as "within spec." my replacement for that has a dead pixel and a stuck pixel (The stuck is hard to notice as is the dead one but they are closer to the center.) At this point i am tired of heading up to the apple store. It seems like more iphones are going to have at least some sort of dead/stuck pixel because of the high resolution. By all means go take it up and they will more than likely exchange it w/o a problem, but chances are the new one will also have a dead or stuck pixel.
