My friend said this kind of application is impossible to build, but i would like to know whether any programmer can do this, the application works like this:
Normally: When someone sending a SMS there will be notification on the sender phone telling whether it is "delivered" or not. I want to override this.
If a phone (let say "Phone A") installing this app, and phone B sending a SMS to Phone A, and Phone B is listed as "blacklist", then the notification in the phone B will not be "delivered", instead it will says "failed" or "pending".
Second, for the call blacklist, It will auto reject blacklisted number, without any connecting sound at all in the caller, not even in mili second.
This application should work flawlessly for symbian like e71/e72, blackberry os 5/os 6, and android 2.1,2.2,2.3
Or if you cant make it cross platform, for which platform can you make? please mention.
