How to read SMS from iPhone Inbox programmatically

After a review of the iOS documentation, I can send SMS using MFMessageComposer in my application but I have not yet found a way for an application to be written suc开发者_运维技巧h 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 read sms from inbox and perform action automatically.

This is not possible with the standard SDK.

You may be able to do this with a jailbroken phone?
