I am working on a version for Nokia Belle and Anna (possibly also S^3, although that has some display issues). It's almost working, there's just a few issues with timeouts due to QtWebKit being rather slow on Symbian that I still need to solve.

Unfortunately you can't upload you own books, it's only possible to use books purchased (or download for free) from Amazon directly. For reading general PRC/Mobi books on the N9 I'd recommend FBReader, the MeeGo port is a little rough around the edges UI-wise, but once you get used to it its quite nice.

If you wish to use an English dictionary to help you read other books you might be in luck though, when you select a word in a book it displays a definition from Dictionary.com:

Unfortunately this only works with English, at least at the moment.
