Multitasking
You can have multiple apps open at the same
time. To open a new app, tap the home button
to return to the Home screen, then start the
new app. Tap the Menu button to quickly
navigate back and forth between previously-
opened apps.
Note
To extend battery life, it is better to close an app when you’ve finished using
it. Do this by either pressing the Back key until it closes or the Menu button
and selecting Exit (if available).
