I understand the native app in the new OS is able to do synchronization. I am wondering if a third party app can also accomplish similar task, has its own settings page where a user can create and configure emails using Exchange server - independent of the OS's native mail and calendar app. Furthermore, is it possible that synchronization be done as soon as a new mail arrives in the server or when a new calendar entry is added. I have tried researching with the keywords {iPHone, sync, activesync} but so far they don't point me to the right direction. Is there an existing app or source code which I can present to my boss as a proof-of-concept? Please help. Thanks.
