Your suggestion for a pro quality video camera with great audio under $500?

I work at a trade school we we have weekly guest lectures, presentations, and other events, and we're wanting to take some quality videos to put on our site and elsewhere. Typical iphones and other similar devices are just giving us poor quality, especially audio, so we're looking for suggestions for a quality videocamera under $500, with the most important attribute being good audio pickup.

Does bbm charge you on iphones?

Hi on an iphone i know you can get bbm for free,
i'm on contract and i get like so many mintes and texts blah blah blah, but i don't get any internet/data… So if i'm out the house and out of my Wi-Fi range does that mean it will charge me?

What is wrong with my mac and what can i do?

OK, so my cousin was in my house and I was using my Mac book pro. As my Mac was charging she also connected her phone charger which I think was not even an official apple charger for Iphone 5s and after that something popped up on my screen and with out giving me a chance to read it, the whole computer shut down. I then checked my the charger and it was green and flashing yellow at the same time. I called the apple store and they told me to do shift control and power button and then turn it on and it didn't work. So I think 2 days past and I plug the charger again and try to turn it on and the light doesn't even show up on the charger and in the side where the green light show when you press the button to check the batter doesn't turn on.

So I just want to know what's wrong with my computer and how much do you think is gonna cost for me to fix it?

If I use findmyiphone to remotely clear my device will that prevent it from being activated?

I'm selling a broken (water damaged) iPhone and I can't clear it myself because I can't turn it on. The person buying it apparently can fix water damaged phones but they want to activate it when it's fixed. I want to know if I can set my phone to clear when it's connected to Wi-Fi or data (once they turn it on) and that won't prevent them from activating it. I don't want to send them a phone that will be useless when they get it but I also don't want to send all of my personal information to them if they can get it turned on somehow.

Please answer from experience

Transfering music from iPhone to mac?

I have a lot of music on my phone that I want to download onto my mac. When I plug my phone in, I can listen to the music that is on my phone in iTunes, but I have no option to transfer my music. I have no music on my mac. Not all of the songs are on the iCloud, whatever that is. I just want to get music from my iPhone to my mac. I have tried everything obvious, it has been three months, and no one has given me an actual answer as to how to do this.
