UILocalNotification alternative for iOS3

I am building an iPhone application and I want to use UILocalNotification to schedule an alarm for an event. The problem is that UILocalNotification only works from iOS4, and I want to try and make my application compatible with iOS3 too.

I have found a way to detect if UILocalNotification is av开发者_高级运维ailable on given iOS version. I am now wondering if there is an alternative for UILocalNotification that can be used on an iPhone with iOS3 to schedule an alarm or notification.

Push notification are your only option.

They requires a network connection, a server of your own and are way more complicated to implement then local notification but are the only way to go in iOS 3.
