Application Navigation
From MobileDesign
Application navigation is the first place where developers from the desktop world get in trouble. Even if connectivity, cursor navigation, and text input were the same as the desktop, the small screen means that less information is displayed on each page or screen. If all the information from the desktop screen is valuable for the mobile device, then the extra information has to go somewhere, typically another page or perhaps the same page accessible through large amounts of scrolling.
These patterns identify some of the common navigation issues faced by mobile applications.
