The app should have the following fields to modify be the user:
-User name
-Password
-Server (the server URL of the service)
-Synchronisation: (select from a list: Every hour (default), Every three hours, Every day)

The app should then synchronize every x hours the contact data from the service with the local contact data of the phone.

For every contact from the service an ID is provided - this should be used to identify existing contacts to check if they have to be updated
