I needed one of these and I was afraid to buy one because I didn't know if the Paperwhite 3G was different from the Paperwhite.

holycrapitsjeff took the leap for me -- and it fits!

This thing even turns the Kindle on and off when I open and close it (and yes I did check this repeatedly because why not).

Thank you! Now my Kindle won't get scratched up by my keys. :D
