Okay so I have a jailbroken iPhone 2g version 3.1.3 (I know, old) anyways, I hate how an SMS pops-up on my lockscreen and my dad is nosy so he reads it. Its a lockscreen right? So it should be secure. Is there a cydia app that blocks all pop-ups from appearing on my lockscreen? By the way, I already have StatusNotifier so I just need that Pop-up blocking app.
