It is available for almost all devices and platforms, be it Windows Mobile OS, Palm OS, Symbian OS, UIQ, Blackberry or whatever. A PC version is also available to read e-books on computer.

Other benefits of this application are: you can also browse and see offline HTML web pages (limited functionality), there is an e-news section where you can read news about newly released ebooks etc.
There is also another free software called MobiPocket ebook Creator for Windows, available on this site (download from here) with which you can create your own e-books with text, images etc. So start reading prc e-books on your mobile……Happy reading
