So I have noticed that when I gently press on the upper-lefthand corner of my iPhone 3g, it feels like I am able to press the glass screen into the housing ever so slightly - however, the other 3 corners feel rock solid compared to that one. Also, when slight pressure is applied to the upper-lefthand corner and the top of the lefthand side of the phone, it makes a "click" noise sometimes that sounds like the glass is clicking against metal or something strange like that. Is this such a small complaint that I shouldn't worry about it, or should I take advantage of my 1 year warranty with Apple and send it in? My concern is that the techs won't be able to replicate or understand my issue if I do send it in because it doesn't make that "clicking" noise all the time when you press on it. Just to clarify, the amount of pressure I apply to the screen to make this "clicking" noise is almost negligible, in other words, it can almost, almost happen from normal operation, since you barely have to touch the iPhone.
