Yes, definitely deregister it before you send it to your buyer. You don't want it to be associated with your Amazon account or they will be able to buy books from the Kindle on your account.LADennis said:I just ordered the new Kindle 2. I already have a Kindle 1 but sold it today on eBay. Do I need to deregister the Kindle I sold on eBay? What happens when you deregister one?
When you deregister a Kindle, you no longer have access to the Amazon books you bought from that Kindle but your books always stay on Amazon. So, when you register your new Kindle, you can download all the books in your Amazon media library.
When I sold my Kindle 1, I deleted all the books from it, took off any personal information, and then deregistered it. I found out later that if I had left my Amazon books on the Kindle and then deregistered it, the new user could have read those books until they were deleted from the Kindle and then she would not be able to access them from Amazon any longer.
Hope I didn't make this sound too complicated. It's really rather simple when you do it.
Enjoy your new Kindle!
