Hacking laptop/iPhone camera?

Hi. Is it possible for a hacker to hack in your laptop or iPhone and watch you through the cameras. Once I heard it on documentary that one hacker hacked in through someone's laptop and took away the privacy of women. I'm wondering if that is possible through the iPhone. Also the pictures we store on iPhone, can it be viewed by our Internet company. Just want to be aware of the rules.

It seems like left speaker on iPhone 4 stopped working?

I just bought this phone a week ago, brand new, out of the packaging/box. I have not dropped it at all and I don't toss it around. I'm very gentle/careful with it!

I noticed that the left speaker doesn't have sound coming out of it? I was playing a game and then had moved my thumb over the right speaker as I was holding it with two hands at the moment and then that's when I noticed no sound from the left speaker. I also don't play music on it, or even have the volume on high ever so it's not like I ''blew'' it or whatever. I don't know. Any idea?

Added (1). Well that's good to know! Lol I thought that's how it was, but a friend of mine told me they're both speakers so I was kind of confused, but now I realize obviously one of the two are used to talk on the phone lol duh. >_< thanks!
