About multitasking
Your BlackBerry smartphone supports multitasking, which allows you to run more than one application at a time. During a call,
for example, you might want to switch to the Calendar application to view your appointments or switch to the Contacts
application to look up a contact. While you are playing a song, you might want to switch to the Messages application to reply to
a message.
There are also shortcuts for most applications that can help you to perform common tasks quickly.
Note: The more applications that you have running, the more storage space and battery power your smartphone uses. To
optimize the performance of your smartphone, try to close applications when you are finished with them.
