What are the built-in options that we have for PIM-syncing?
- calendar
- contacts
- tasks
- mail
- rsync for files
Which sync protocols are supported out of the box, which ones can be added by applications? It would be nice to have an overview of these things. To be honest, I don't have a very clear picture of how this works in general: do some syncing protocols need to be supported be the OS, or can any kind of syncing be just added by an app? For instance, if Jolla won't make DAV support (webdav, caldav, carddav), does that mean we're stuck with other protocols, or can we just build some apps to support it?
Nokia used to have Mail for Exchange or Ovi sync (discontinued and never worked well) built in - both not exactly awesome, but in some videos I've seen Exchange is still one of the first apps you can install.
