2nd generation and 3rd generation different sizes
As you can see in enclosed photos ( 2nd generation is smaller and 3rd generation bottom), there is a bit difference between the two. I was told my the rep I spoke to a few days ago that they were same size and that my cases would fit the 3rd generation, so I was a bit annoyed at seeing the difference. So now I have to recycle my old cases and get new—jeez!
