About synchronizing your organizer data
You can synchronize your organizer data between your BlackBerry® smartphone and your computer to keep the data the same in both locations. If wireless synchronization is not available for your smartphone, or you have turned it off, you can synchronize your organizer data using the BlackBerry® Desktop Software instead of over the wireless network. You can turn off wireless synchronization for each organizer application on your smartphone. This feature isn't available for the BlackBerry® PlayBookTM tablet.
Organizer data includes your calendar entries, contacts, tasks, and memos. You can set options for each type of data, such as the application that you use on your computer for your organizer data and how you want to synchronize your data.
