About exchanging it...
I went to an Apple store this weekend and asked the so-called "genius" about two things:
1. Why is my screen tinted yellow and of such low contrast and can anything be done with it. First thing he does is turn the brightness up on my and my friend's iPhone 4S (which does not have the yellow tint nor battery issue) to "compare them". I mention to him that I never never have the screen at anything more than 25% brightness because the battery drains even faster. His reply, "Well, is the tint preventing you from using the screen?"
2. Shocked by his answer, I then asked him about the horrible battery life on my phone. His reply, "Apple is working on it. They'll fix it or if it's a hardware issue they'll take care of it."
He didn't even offer to replace the phone even though that's the store I bought it from the day after it was released. This may be the last Apple thing I ever buy. Plus, I noticed that they no longer have Mac Pro's on display in the store; it's iMacs all the way on one side and MacBooks on the other. Go figure.
I think this weekend I'm going to go in there and ask him about the rattle near the camera lens. Maybe he'll ask me if the noise is preventing me from using the camera. Genisus were so much better in Apple stores years ago, now they're all attitude.
