KINDLE: Why can't I deliver my Kindle book directly to my device?

There are several reasons that you may not be able to deliver your Kindle book directly to your device.

1. Your device hasn't been registered with your Amazon ID.
2. Your device does not have Wi-Fi capabilities (3G requires a USB connection to your computer).
3. You have chosen a Kindle book from Penguin Group publishers (Penguin Group prohibits wireless transfer from Amazon.com to your device.)
