I was hesitant to host a copy of the app, but then I learned that it was everywhere, including Aldiko's own support pages. And it's simply too useful not to share. I happened across this copy back in late December 2010. Aldiko 2.0 was just getting into the Android Market and I had been bugging Aldiko about letting me have a copy so i could try it. I ended up trying to install 4 different copies and this was the only one that worked. It was an early version of 2.0, and the rest were from later builds. They all required Android v2.1.
