I’ve bought a Kindle DX from Videopro Com Pte Ltd (which is the only shop that carry Kindle) recently. I noticed that in the settings, there is already a name appeared in the Registered User, Device Name and Device E-mail (the particulars belong to the owner of the shop). Why is this so? Is there any reason? How do I know whether the Kindle DX is a US version or International version? The serial no.B009A1A002531F13. I understand now that I’m not able to purchase any books thru Whispernet because Singapore is not within their recognized zone. How to go about it? The reason why I bought Kindle is because I read fantastic thing about it. I’m lousy in all these technie stuff. Can you help? Appreciate very much if you can.
