Applications with desktop synchronization
You can use the BlackBerry® APIs to build applications with desktop synchronization capabilities, such as reference guides and organizer applications. The user connects the BlackBerry device to a computer to manage and synchronize data that is located on the computer.
Research In Motion® does not provide HotSync® conduits or any other direct database synchronization module. You must build the synchronization code, and the BlackBerry device user must initiate the data synchronization process manually. After the application is installed on the BlackBerry device, the BlackBerry device user must synchronize information manually by connecting their BlackBerry device to the computer with a serial connection, a USB connection, or a Bluetooth® connection.
