I have noticed some pixel-walk on my iPhone, as some others here have had. I set a background (uploaded here) to test for flickering. At first I didn't really see anything. Though today checking again, I could see some slight flickering. Perhaps it has gotten worse, or more likely, it is lighting/temperature related. I am unsure as to what amount of flicker is considered normal. As stated, there is some slight flickering - that is, not too intense. I do certainly get the vertical line appearance upon relative motion between the iPhone and my eyes when the viewing distance is less than about 12 inches. Its hard to know whether or not this would be considered a defect given the undetermined's of my eye sight. Perhaps I see very well at close ranges. Then again, I see no pixel-walk on my MBA TN panel. Id guess the "observed" width of the vertical lines seen look to be about 3-4 pixel widths.
I purchased the iPhone from Walmart (AT&T carrier); if I wanted to get this exchanged, how should/could I do so? I don't assume there is the need to exchange all the accessories - just the phone minus the sim card.
