I've only had my iPhone for about 3 weeks now (I got it late.. thanks AT&T) and it has been working great! Well, except for one thing. The button on the top of the device, the one that controls power, etc, has become somewhat depressed into the iPhone itself. It is almost as if when I pressed the button down one time that it decided not to come back up. But this isn't a single time thing, it has slowly been depressed into the device. Currently it is still totally functional, but a) has anyone had a problem like this (if it can be called a problem) and b) since I am still under warrenty does it seem worthwhile enough to go get it fixed/get a new iPhone. Also, would this qualify as a serious enough issue to justify in a fixing/replacement? Thanks for your help!
