Photos on iphone photo stream and cloud?

Ok sorry if this is a dumb question but I just want to be sure of things.

In a few months we're taking an anniv trip to Disney. Normally I leave my iphone turned off in the room to avoid work calls and drama and just take my regular camera. This year however we're using their new app and it has all our reservations and plans in it so I have decided to leave the camera at home and just use my iphone camera this year.

Here is my question… I take tons of photos but clearly with all my music, apps, etc on my phone it can't hold everything. However, if I understand correctly I can take photos all day then when we get back to the resort flip on my Wi-Fi and load the photos I want to the folder I have made on my photo stream (already have it set up on my home computer to view). I can then delete them from my camera roll to have space for the photos for the next day.

Then when I get home I can pull up my cloud and the photo stream will have everything I loaded via Wi-Fi. Right? Deleting them from my camera roll does not delete them from my photo stream. Right?

How much is the iPhone 4S monthly?

Okay so ether for my birthday or Christmas i'm gonna a iPhone 4S. I'm trying to find the monthly price. I'm only 14 years old and I'm finally getting my first phone. I'm going to get it for Verizon. I'm just sort of confusing about pricing. I have been making my own money and I'm going to be paying for the phone.

All I would like to know is, how much is the monthly bill? I've been searching the Internet and I'm kinda getting confused so. What the heck is a termination fee? I have no clue. For this phone I probably will get the 2 year contract.

I'm sort of confused, any advice?

( my parents never told or talked to me about this they just went on vacation so I'm stuck in the house for a week and they won't pick up there phone.)

What's the difference between data and Wi-Fi in a contract?

I'm planning to get an iPhone 4s, and it comes with 100MB data and 2BG of data.
What's the difference? Is it like if I use all my data I have Wi-Fi to fall back on, or is it that data is when you're not connected to Wi-Fi! I'm so confused! Also is 100MB enough?

Iphone as wireless camera monitor? - 1

Asked this once before, didn't receive an actual answer.

I'm an independent filmmaker and have recently helped out at a larger scale film shoot downtown. I noticed that a producer had her iphone out and it had a live monitor feed of what was being shot! When i look it up online people say it isn't possible. But I saw it with my eyeballs, so it is.

I know the new GoPros have a Wi-Fi remote app feature, but i'm not talking about that.

I have a Canon DSLR camera.

How does this work and how can I do this?

To clarify… I was not able to speak to the producer that day, and I want to know how to do this for my own films with my dslr (which has a mini hdmi output)
