The Penguin US iPhone application allows you to enjoy Penguin content and news on your iPhone. The iPhone app also includes excerpts that can be read on- or offline. You can download the app, for free, directly from iTunes.
Penguin has also created an optimized version of its website for mobile devices. This site can be reached directly by going to mobile.us.penguingroup.com on any Web-enabled cell phone.
Both the mobile site and the iPhone app allow you to read (and comment on) the Penguin blog, listen to the Penguin podcast, as well as browse new titles and special interest areas. Later phases of Penguin Mobile will allow users to shop and buy directly from their mobile phone.
