I just noticed that the button is flush on the left side and only sightly raised on the right side. This makes it a little difficult to push, especially because i have it in a case. I have to push the button on the right side for it to work. Do you think this warrants an exchange? Otherwise the phone is flawless. Not sure if I want to risk the yellow screen phones. Would I have to make an appointment at the Genius Bar? I hate how you can only schedule a couple days in advance and they are usually booked. Thanks.
