Im about to start an application that will allow the user to set up a blacklist and a whitelist for SMS msgs. The app will grab any SMS msg going in/out of the system and check if it is allowed or if its blocked. If its blocked, it will either not tell the user that they received a SMS (incomming) or it will not send the SMS (outgoing). The problems I think I am going to run into are with getting control when an SMS event occurs. I know there is no notifcation for such an event, so I cant register to receivce a launch code. I am thinking I will need to trap system calls to do this, but I can see there might be problems with this. The documentation says never hack a trap address for good. This is what I would need to do since my app cant be running all the time. Will changing a system trap address to a function in my code cause problems? I would set the trap address at install (when the user sets up the app for the first time) and somehow (havnt thought it through) restore it if the app is deleted. Can anyone give me some insight to how this might change the system, and if it is safe to do this? Any info on the subject would be great.
