Yes there are several stock apps like that.I don't think there is...but there is a jailbreak tweak...using passcode to lock apps. There is no jailbreak tool for iPhone 4S yet however.
I don't think so. I know spycalc doesn't. Haven't had much use with kyms. I don't think stock phone will allow you to divert calls or texts. Jailbreak will allow you to do that.So how do the way work if someone is calling your phone? Will it hide calls and text messages?
You could save this to your phone as your wallpaper...I just got the iPhone 4s I was wondering about any good message hiding apps. My girl goes in my phone all the time. Please someone help. I need some simple and good.
