I am looking into a final year project for university and im exploring all possible options. I was thinking about SMS encrypting but with an iphone. I think its possible to send an SMS message via any program I make for the iphone but if i did make said program, would it be able to intercept enrypted messages; instead of those text messages going to the standard SMS program?
I ask this because I know that Apple are very strict about their products and the last time i checked the only way to use another text program was to jailbreak the iphone and I am not keen on doing that.
Thanks for your time
This is not possible without jailbreaking and fiddling with the private APIs, and furthermore, it is against Apple policy. Even with jailbreaking, it is not trivial.
