Is the BACK PLATE of anyones CLASSIC coming APART?

I feel like it from using the headphones at the gym but the back of my classic kinda coming apart. it sucks because then the light sensor doesn't work and the keyboard only comes on if i squeeze the back together. ATT sucks and said warranty wouldn't cover it even though there wasn't a single dent on the corner where its peeling off (at least wen i brought it to them, after halloween is a different story)

And suffice to say its annoying and I tried crazy glue and it only lasted a day.

1. you think i should take it to one of those repair guys in the mall AND/OR

2. do you know of a specific type of glue that would work?
