ios4 - react on incoming sms on an iPhone

Question

After researching the possibility to read incoming sms programmatically i realize that it is not possible on a standard iPhone.

I am researching an application which should have the following sequence for action:

1. User#1 send an sms to User#2 with a specific keyword, maybe &&XX&&
2. User#2 receives the sms and based on the keyword something should be triggered

Given that it is not possible to get the phone to act on the sms-based keywork automatically it may be possible to trigger something manually when the sms is received and us the sms as input.

My question is if someone have any ideas what is possible or/and what the best method would be to use the sms as input in the simplest possible way.

Answer 1

No, on a non-jailbroken phone, you cannot get any data on SMS messages or phone calls. They are entirely walled off from your application.
