I've been developing an iCal Service that publish an ical file as an URL, so I can easily subscribe to this URL and I will get out-of-box all my events, alarms and todo's.
The problem I'm facing is that I can't create a new event back to my subscribed calendar, unless I use Mozilla Thunderbird (with Lightning) as any other calendar application gives me no change to add a new event or edit an existing event.
All apps seam to treat Subscribed URL's as Read-Only Calendars.
Can anyone give me a Why or any App that gives this ability?
I even bought some 3rd party calendars for iDevices and no one gives this ability as well, neither desktop apps suck Mac iCal or Outlook, or any web app such Google Calendar.
Any help on this matter is greatly appreciated.
