After a review of the iPhone SDK documentation, I have not yet found a way for an application to be written such that it can programmatically process the content of an incoming SMS message within the iPhone platform. The idea would be for such an application to be running in the background and based on specifically formatted SMS messages would be able to take specific actions.

Does anybody know if this is possible with an iPhone SDK application and if so, provide a pointer to information about how this can be done?

Unfortunately, you cannot intercept - or be notified of - incoming SMS messages with the iPhone SDK.

One possible alternative, is to register a custom URL scheme that launches your application when a url with that scheme is embedded in the sms message and the user cicks on it.

to set a custom url scheme, you must implement both the CFBundleURLSchemes and CFBundleURLName keys in your application's info.plist.

In your Application's delegate, you can then implement the application:handleOpenURL: method to get any paramaters that were passed to your App from the url in the SMS message.
