BlackBerry device.

4. The BlackBerry MDS Connection Service creates an HTTP session for the user and retrieves the requested Internet or
intranet content from the content server.
The BlackBerry MDS Connection Service converts the content so that the user can view it on the BlackBerry device,
and sends the content to the
BlackBerry Dispatcher over port 3200.
5. The BlackBerry Dispatcher compresses the content, encrypts it using the device transport key of the BlackBerry
device, and sends the encrypted content to the BlackBerry Router.
6. The BlackBerry Router sends the encrypted content to the wireless network over port 3101.
7. The wireless network verifies that the PIN belongs to a valid BlackBerry device that is registered with the wireless
network and sends the encrypted content to the BlackBerry device.
8. The BlackBerry device sends a delivery confirmation to the BlackBerry Router, and decrypts and decompresses the
content so that the user can view it in the BlackBerry Browser.
If the BlackBerry MDS Connection Service does not receive a delivery confirmation within the flow control timeout limit,
it sends a message to the wireless network to delete the pending content.
