I got my iPhone 4 in August 2011, so it is past the warranty coverage but less than a year old. Today while using the Kindle app, my screen suddenly displayed these vertical colored bars and turned off. It wouldn't turn on at first, and eventually did turn on showing the Apple logo with the colored bars on the side. Then it turned off. I tried turning it on again a few times unsuccessfully, before it finally turned on and seemed to be reset (asking me to restore from iTunes or Cloud, etc.). I went to the Apple Store where they did a soft reset which got my phone to turn on normally. After a few minutes of use, the screen crapped out again (started to freeze, then the display got all screwy). They took my phone to do a diagnostic test and determined that my graphics chip/card is dying. They said the only thing I can do is do an out-of-warranty replacement for $149. Since I understand hat's their policy and I AM out of warranty, I reluctantly agreed but I'm just pissed because it seems to me a problem like that is not normal and I shouldn't have to pay $162 (after tax) to replace a defective phone. Thoughts?
