I have a requirement to develop an iPhone app (and also an Android app) to show a calendar which will receive events from a central server, ideally the app will query the server for any new events for that app user. It will be possible to open the event to see the details in the app.
Note I will need the source, not just a packaged app.
Also, not a portal to a HTML5 online app, it has to be a native app.
The app will synchronise with the server whenever the app is opened.
Push notifications will prompt the user towards the app.
If you have already worked on a synchronised calendar function then your advice/direction on synchronisation methods would be useful, the back end is not developed yet so early input would help.
