I got it to work.....I also have a Mac as my main computer. I installed Mobipocket 6.0 on my Eee PC running Windows 7 & it didn't recognize the Kindle 2i. However, I tried it again on my work PC running XP & it recognized the K2i & gave me the PID.
So, yes, I was after the PID of the K2i....and finally have it.
I had previously tried with Mobipocket 6.2 (on Windows 7 & XP) and it didn't recognize the K2i. Also, the python script that I had could have been an old one since it said my serial was invalid. I have another version of that script now, but I am not home yet & able to try it since my K2i has a protective sticker covering the serial & it's on the box but that is at home. I'll try it later since I am curious if it will work with my serial now.
Thank you for the offers of help.
