So it's my 4th getting my iPhone replaced this week! First issue had a very noticeable green tint, second one it turned everyone yellow, third there was a big blob after 20-30 minutes of use. After getting it replaced a third time, as I was walking out of the Apple Store, I noticed that the camera image looked odd. Images looked purple and there was a very noticeable purple and the genius confirmed. I searched and didn't come up with any for the iPhone 4. Just wondering if this particular iPhone was a small minority. Such a shame that I've already had this replaced 4 times in less 5 days and by no means am I pick.
