From the press release:
WikiReader by Openmoko, the popular palm-sized electronic encyclopedia containing more than 3 million English language Wikipedia articles is now more universal than ever. In addition to delving into vast resources of information on the English language version of the Wikipedia, users may now go to http://thewikireader.com to download any of 14 other language versions of Wikipedia including Chinese, Japanese, Portuguese, Norwegian, Greek, French, Finnish, Danish, Dutch, German, Spanish, Welsh, Russian and Hungarian along with the virtual keyboards with characters to support them.
Unfortunately, it's going to nearly impossible for me to update my WikiReader due to the way the software is designed. You see, you can't just download a couple files and copy them over. No, if you want to update the WikiReader you have to download the full 3.6GB and copy that over. I seriously doubt that I could write that much data to a SD card without adding quite a few bugs. And I know for damn sure that I can't download it; my web connection is too slow.
