Mobipocket Desktop 6.0 did indeed give the PID for the K1. But without kindlefix.py, you cannot shift Mobipocket eBooks to Kindle eBooks. So even if you could get the K1's PID inserted into a Mobipocket eBook, the K1 will not display it without changing the document identifier. And this change is what Amazon is upset about.
So basically the message I am getting from Amazon is....
You bought a Kindle, now we own your *ss.
