iPod touch is this normal?

[tidytrev]

hi guys, iv had my ipod touch for about 6 months now and only recently noticed my screen doesnt fit to the bezel, its intermitent and sometimes its fine and sometimes its like this.
is it just me or is this a common problem?
can anyone post a pic of how its meant to look if possible

Yes, that's normal.

You can only see that when there's light shining directly onto the iPod, too.
