Or, you can replace a (maximum capacity) 64GB microSD card with a much larger capacity microXD card (same hardware, but new software extortion protocol required by "SD Consortium"). A single XD card should fit that space, and may be upgraded to higher capacity in the future.

Another benefit of replaceable flash memory is that you can stick a linux swap partition on it. This is MUCH needed for doing anything useful in a kindle touch after loop mounting a filesystem from a file on the USB Drive. The kindle touch does not leave much memory for native mode apps, and a swap partition could help a lot in that case. Running out of memory when automounting a loop mount has caused more than one kindle touch to get "bricked". Luckily, I was able to restore my kindle touch to good health using the internal serial port.

I am a bit afraid to use a swap file on the integrated mmc device. I do not know how well it does write wear-levelling, and wearing it out from too many writes would be a bad thing unless you have BGA rework equipment. [BGA = Ball Grid Array = many soldered connections UNDER the chip.]

Regarding CDMA, starting with Kindle 3G, newer Kindles use GSM 3G modems that work all over the world (except where I need, Belarus, where the "president" and his family own the telephone company and HATE competition -- even Skype is outlawed for communicating with the USA). If you have a newer kindle, it may be usable in your country. Amazon has a coverage map at their website (with a bad all-white blob where Belarus resides on the map).
