This one goes to all those paranoid minds out there ready to create conspiracy theories out of everything. It looks like your friendly iPhone is kind of watching your every action. What it does is take a snapshot of the current screen and caches it every time you push the home button, but only for a few seconds. And since that’s the most important button, since its’ the only one, to be pushed, I’d say you end up pushing it quite a lot.

Is it dangerous for you? Hardly! You have probably more chances of ending up in a local black hole than having your most personal, yet dirty secrets revealed by a smart thief who manages to pull up those screenshots you took with your home button. I know I said it caches them for a few seconds but a mac-savvy mind will find them sooner or later. And I really doubt that a smart thief like that will steal your boring phone instead or phishing for something else.
