On my 4th iPhone 5. First - Black/Slate originally from Radioshack...had ding in back of aluminum by the bottom piece of glass. Second - Exchange from Radioshack, pristine out of the box. However, after a few days I noticed the upper left corner of the screen glass was a bit loose. I could make it flex with a slight click to it if I pressed it. Also had some reception issues with this one. Third - Radioshack wouldn't help me so I just decided to go to the Apple store. Genius noticed my signal and replaced the unit. Fourth - Third unit had some noticeable dings, and I decided I didn't want to keep that phone becauses it was in pretty bad shape. "Genius"(I hate calling them this) exchanged it for me as an exception. Unit is near flawless outside of a tiny nick at the top which is easy to overlook. He said I couldn't exchange it again for cosmetic purposes or signal issues. HOWEVER, the glass on the top of the phone is a hair off, or the outerframe is uneven. Basically, the upper-right side of the glass edge sticks out, enough to feel it with your finger. It also flexes if you gently squeeze it, but doesn't make any noise. The other side doesn't do that, and is even with the body of the phone. Cases don't fit 100% and you can see the raised glass on one side of it. Not sure whether to stick with this one or try to contact someone higher up...I'm pretty tired of going to the Apple store and I'm sure they're tired of seeing me. I honestly feel an overwhelming majority of these phones have some sort of flaw, however big or small. Whether it be cosmetic or not, this is very alarming for such a big ticket item whos manufacturer boasts such flawless inspection and quality of their products. I wasn't looking to find anything wrong with these phones, they were just noticed from normal everyday use. I guess this is just normal.
