so i just received my 3rd 30gb ipod from apple because of previous defective ones and once again the ipod they sent me is having a problem. it has the same the problem as the first ipod i sent in, which is that the metal bottm is coming off a little bit on the left side of the white face. there's probably a millimeter gap now, so i don't know if anyone's experienced this before. i don't know if i'm nit picking too much or if this is another legitimate problem that i should have apple address. i guess i'm afraid that any sort of liquid could get in there and damage it. have this happened to anyone? this is the 2nd time for me.
