Multitasking
Multitask simultaneously with voice and data—
browse the web, play games, send and receive
messages, and listen to music, all at once.*

another, press the Multitasking Key and tap Home.
From the home screen, you can initiate another task
without closing your current one.

Key. You can then tap an open task to select it or tap
Main Menu to access the main menu.
3. To end a task, press the Multitasking Key and tap
next to the task you wish to close.
*Music and voice applications cannot be used at the same time.
