❑ Launching: While the built - in applications are all launched from the main Springboard screen of
the iPhone and iPod touch (see Figure 1 - 3 ), Web developers do not have access to this area for
their applications. Instead, a user can only access your application by entering its URL or by
selecting a bookmark from the Bookmarks list (see Figure 1 - 4 ). Unfortunately, there is absolutely
nothing a Web developer can do to emulate the native application launch process.
