So, quite often I'll hear of people talking about their iOS devices being hacked. They say things like somebody is remotely accessing their iPhone, changing things around and making calls, texts or browsing websites in safari, etc. I've always just assumed they're full of crap and they're just the type of person who's got all these conspiracy theories. Is there any validity to these types of statements? If yes, how is somebody able to remotely access another user's device?
