I would really like to know exactly what is being changed. My DXG is currently using 3.1 from Yifan Lu's kindleupdater.zip so Amazon will never apply the critical update. I had given up hope of using the 3G.
I also have a K3G using 3.4.2 and am trying to get the critical update so I can find out what they are changing. If they are only changing the certificates then I could copy them into my DXG. When updating to 3.4.2 I happened to intercept an OTA update:

FWUOupdate-06-558700031-611680021.bin.partdldtmp.partial

I wonder if that had the critical update? Does anybody know exactly what is changed with the critical update?
