Tx2ph

tx2ph is a book-reading service for Internet (WAP)-enabled mobile phones and PDAs. Unlike Java-based software for reading ebooks, this service is based on the devices' built-in browser, hence no need to download and install anything (thus avoiding compatibility issues).

It is capable of rotating the text 90 degrees so that the lines run along the longer side of the screen, making the text more readable on smaller screens (like 176x220).
