Would you download this app?

What's up guys? So really quick, I wanted to know if this app has any potential. You guys can steal it, I don't care. Basically it is an app that is predominantly for iPhones (even though I don't like iPhones) because they don't have a removable battery. Basically, it would require a passcode to turn off your phone, put it on airplane mode, etc. Long story short, YOU have to be the person who disables any connections from it. This way, if someone is to steal the phone, they can't turn off the phone or the services, and that way you can track the phone with a downloaded app. Would it be a good idea?

Yes, it's a good idea. But it's annoyed of requiring a passcode to turn off or put on airplane mode.

I think the most effective way to find the lost or stolen iPhone is via ICCID (Integrated Circuit Card Identifier)

I think not, the phone powers itself down in 5 min unless for some reason you set it to never.

So if you have a decent passcode from the start there's no need for it, what are you going to do have a different code for every option? Doesn't seem like a good idea.
