6. The BlackBerry device sends a delivery confirmation to the BlackBerry Synchronization Service for each record that it

receives.

7. The BlackBerry Synchronization Service receives delivery confirmations and deletes the corresponding synchronization

request entries from the SyncRequest table, and writes an entry to the SyncRecordState table for each delivery

confirmation.

Each organizer database record has a unique identifier that is mapped to a corresponding record on the BlackBerry

device.

Process flow: Adding a contact picture on a BlackBerry device

1. A user adds a picture to a contact in the address book on a BlackBerry® device and saves the change.

2. The BlackBerry device creates a changelist request to synchronize the changed record. The changelist request includes

the updated record information and identifies the address book as the target for the update.

The BlackBerry device compresses and encrypts the request, and sends the request to the BlackBerry Dispatcher over

port 3101.

3. The BlackBerry Dispatcher uses the master encryption key of the BlackBerry device to decrypt and decompress the

request, and sends the request to the BlackBerry Synchronization Service.

4. The BlackBerry Synchronization Service receives the changelist request, writes a synchronization request entry in the

SynchRequest table of the BlackBerry Configuration Database, and sends the changed record to the BlackBerry

Dispatcher.

5. The BlackBerry Dispatcher sends the changed record, in XML format, to the BlackBerry Messaging Agent.

If the file size of the picture exceeds 32 KB, the BlackBerry Messaging Agent rejects the synchronization request.

6. The BlackBerry Messaging Agent sends the changed record to the messaging server.

7. The messaging server updates the user’s personal contact list.
