Data flow: Receiving email on an 
iOS
 device using the 
BlackBerry Secure Gateway

This data flow describes how work email and calendar data travels between 
iOS
 devices and the 
Exchange ActiveSync
 server using the 
BlackBerry Secure Gateway
.
Diagram showing the steps and components mentioned in the following data flow.
  1. The device issues an HTTPS request to the mail server and requests that the mail server notify the device when any items change in the folders that are configured for synchronization. The request travels through the encrypted and authenticated channel between the 
    BlackBerry Infrastructure
     and the 
    BlackBerry Secure Gateway
     to the mail server. 
  2. If there are no new or changed items during this interval, the mail server sends an "HTTP 200 OK" message to the device. The device issues a new request and the process starts over.
  3. When there are new or changed items for the device, such as a new email or updated calendar entry, the mail server sends the updates to the device through the secure channel between the 
    BlackBerry Secure Gateway
     and the 
    BlackBerry Infrastructure
     to the email or organizer app on the device. 
  4. When the synchronization is complete, the device issues another request to restart the process.
