View the GUI, you may confused, it's so hard to use, please pay more patience.
PID: any ebooks has one PID binded, it's hard to find. Search it on Google.
Kindle Serial Number: To confirm which Kindle you have, look at the serial number on the back at the bottom (for Kindle 1, it's under the back cover). You should also be able to find it on the Kindle packaging. Since firmware 2.5, it is also shown in the Settings page on your Kindle. This is also the only place you'll be able to check your S/N on a Kindle 3. View Wiki.
Kindle.info: It contains all PIDs, when Kindle for PC/Mac installed, the file will be created.
If you transfer books from Kindle Reader, then input Kindle Serial Number, if you use Kindle for PC/Mac to sync the books to computer, then you need to find PIDs or Kindle.info.
If you can't find the PIDs and Kindle.info or have some trouble with this script, please use the Method 3 as below.
