This is probably because K3 and K2 have different drm mechanism or different API. Either case, since you got both k2 and k3 binaries, it is possible to find a work around if you do enough reverse engineering. In the worst case, you can emulate or dual boot to k2 from your k3.
Otherwise, you have to change sn
Well reverse engineering stuff is hard to do. We don't have both binaries. We only have the version 2.5.8 DXG active content binaries as there isn't such a thing as version 3.2.1 DXG active content. So we can't compare.

What i have is the same active content purchased for my kindle 3 for firmware 3.1. But i don't think we can compare and find the differences because 1) They are on different firmwares (3.2.1 vs 3.1) 2) They are DRMed for different serial numbers (that is more serious than issue 1

If only we had 2 active contents DRMed for the same serial number but one for firmware 2.5.x and one for 3.x.

I once asked yifanlu about a dual boot he said he doesn't have enough time and put some instructions about the ones who want it. You can search Yifanlu's thread for the instructions.

The real solution might be the changing some parts in the source of the 3.2.1 firmware for kindle DXG. We need to edit the part where kindle tells amazon its firmware. The firmware should tell itself as 2.5.x to let amazon download active contents for our kindle. For now it registers itself as below 2.5 so we can't download active content.

That doesn't solve all of our problem. Then the firmware should behave like it is 2.5.8 when opening and registering active content. What i mean is it shouldn't look for a 3.x active content it should look for a 2.5.x active content. This part may be really hard.

The only solution without changing SN (and abandoning free 3g) seems like waiting for the open source kindle 3 firmware for kindle DX and 2 https://www.mobileread.com/forums/sho...d.php?t=149166 which you work on and changing the appropriate parts i mentioned above (if possible).
