This is weird on the back of my case there this little smuch as if it got rubbed to many times as I tilt it alittle looks like a little tint of lightly peachy color cant explain it I have my ipod touch in a case so I dunno if the rubbing on the black case I have that has anything to do with this. I dont want to think that its because of any sort of rust Ive used water on my ipod to clean it only damped water from my white shirt but quickly dryed up not like soaking wet shirt.... I also notice in the front on the upper front it feels kinda i dunno empty. When I put my fingers around the corner upper right or left it likes to do this little click sound to it when im cleaning my ipod with a cloth.. i.e. White shirt. Has anyone notice this sound on there ipod touch on the upper area if you even tap your finger on it your notice it sounds kinda empty in that area if it does it to you... But thoughs are my two questions.
