Integration of iOS devices (iPhone / iPad) with Sogo

The Sogo documentation describes what options you have to sync with your iOS device
With iPhone 3 you can use the calendar directly via caldav connetion (Look at the documentation about potential problems)
With iPhone 3 you have to use SyncML for your address book
With iPhone 4 and iPad you can access the address directly via Cardav, but you need to open/configure port 8800 and/or 8843 on the server too
