How can I launch the application at the specified time on the iPhone?

I am developing a to-do list application. I am looking for any way to warn the user when a task will be called, even if the application is not running. Is there a way to install the program at the specified time without user intervention? Or a way to trigger a warning anyway?

No, until the push notification service is released.

Your best choice right now allows users to add reminders to the Calendar - without a push service, there are no notifications without an active application launch.

As was clear from Steve Jobs himself, the iPhone SDK will NOT support background processes. In addition, there is no API for accessing the calendar on the iPhone.

If these things are important to you, you should file a promotion request: Apple Bug Reporter

But even after push is issued, this will not allow the application to notify the user on its own. You will need to start the server, which will trigger notifications for people as soon as the task approaches, which means that you will need to have a list of all tasks synchronized with your server.
