I hope that you might all have heard about the kindle from Amazon. It is a device used for reading Ebook. There is also a Kindle app available for computers. Right now I am using ipad as my primary device for surfing and reading Ebooks. I have recently downloaded the Kindle app for this. I really want to buy an ebook. But when I tried to purchase it prompts me that I haven’t registered the device yet. I have followed the instructions to register my ipad but it keeps me telling the same. Why is this so? How couldn’t I able to purchase the ebook even after creating account for it? Any suggestions over it.
