To be fair to CleverClothe, he's not technically wrong on a semantic level (or so my identical online cousin told me when I asked him).
A device PID is still generated... it's just not used (or used by itself) to encrypt Amazon books anymore. You used to have one master device PID that worked for every single book that you purchased for that particular Kindle. One PID to rule them all, so to speak. That changed when the 2.5 software was released (hello?? collections?). From that point on, there were unique PID's
for each book that were generated from a combination of hardware details and metadata tokens in the ebooks themselves (which was how K4PC worked from the start). All I was trying to say was that the old device PID that you had to generate from the "kindlepid" script doesn't have f**k-all to do with removing the DRM from Amazon purchases anymore.
I'd like to thank everyone for coming to the defense of the guy that apparently uses the same username/avatar as me in other corners of the internet.
