Update: Please note that this article has been written at a time where mobile phone displays were small and bad, and apps almost non-existent. The books offered by the service are available as Java jar files. This means that you cannot play them directly using modern ebook reader apps. Check out Project Gutenberg as an alternative.
Reading books using a mobile phone is probably not the most pleasant way but it surely is better than sitting around doing nothing at all.
Books in My Phone provide hundreds of books that can be downloaded and transferred to your mobile phone. You can chose between two methods to transfer selected books to the mobile phone.
You can either download the books to a computer and transfer them afterwards using the normal means of connecting the mobile phone to the computer, or by using the phone's mobile Internet connection to visit the website directly and load the books this way to the device. The second option is probably only advisable if you have a free data contingent. Books are not overly large though.
The books are optimized for mobile phones, some of the features are:
I would say the books are mostly classic literature books from authors such as Charles Dickens, Jules Verne, Joseph Conrad and Sir Walter Scott. All books are out of copyright in the United States which means it is perfectly legal to download those books to your mobile phone.
Two versions are always offered. The first offering a better reading experience but requires a modern phone while the other does work on older phones as well. I would try the first version and see if it is supported by the phone and only if it is not supported I would download and use the second version.
