Rather than struggling with a bunch of old command-line scripts to calculate the Personal ID (PID) of your shiny new Amazon Kindle, I’ve released a super-freakin’-easy webapp to do it for you in a matter of seconds. No joke.
Simply visit http://kindletools.prestonlee.com, follow the instructions, and be sure to gift me a short novel to say “thanks”. 🙂
Update: See Jer’s post on the bigger process of converting Kindle books.
