I have for sale my Kindle Keyboard 3G.
I am selling it as I don't use it anymore due to me having the Nook Simple Touch.
It has a slight fault of an ink blob which you can see at its' worst in the photo I have uploaded. This hasn't bothered me and you can still read even with it there.
The 3G will allow you to use email and internet on the Kindle - which the new Kindle 3Gs won't let you do - this will also work abroad in certain countries too.
