If you check the Amazon update site, you will notice that they stopped building Wifi and Wifi+3G updates before the K5 (5.x.y) firmware.

One build does both (or either), the kernel enumerates the networking hardware at each boot.

I am not sure what you are asking about, being a hardware or firmware limitation.

The connector is mini-PCI-e :

The Kindles only use the USB interface to the radio/modem not the PCI-e interface.

Also notice that manufacturers often re-purpose the otherwise un-used pins in their card design. (shame on you Asus)

But "by the book" the only thing you can count on is connecting the USB host connection on the connector to a USB flash drive (up to 128G byte storage add-in).

I think the correct name for the 8 pin critter is: UIM card (Universal Identity Module) rather than the 6 pin critter: SIM card (Subscriber Identity Module).
