How to take good motion pictures?

Hi! How can I take good dance pictures? My friends and I were going to have a photoshoot, hoping to get good pictures of side aerials, front aerials, tucks, tilts, leg holds, calypsos, barrel turns, drop tilts, knee drops, etc. (for those of you that don't know what those things are most of them are in motion. They are flips and jumps.) We will be using iphones… Do you have any tips on taking motion pictures with an iPhone?

How to fix my iPhone 4 (partial water damage)?

Okay so I brought my iPhone 4 into the bathroom with me because my friend was texting me, and I accidentally dropped it into a bucket of water which had soapy toilet cleaning solution in it. Thankfully, only the bottom cm (where the speakers and plug in is) was submerged in soapy water goo. I cleaned off all the goo from most of the outside and used a tooth pick and a Q- tip to clean the soapy goo out of the speakers and outlet. When I turned it on, it operated as usual, except for a few things…
1. After i typed in the passcode, the usual "click noise" didn't happen.
2. When i went on the youtube app and the music app no sound was made.
3. No sound was on any games or apps except for voice memos.
4. No noise was made while typing (no usual clicking)

but the ringer still worked but not for texts. I turned it off and put it in a bag of rice but i'm not sure what else to do.

How to make the background to a picture black?

I want to make the background of my picture black, but I don't know how. I don't have Photoshop, so I can't use that. And if there's anything I can do on my phone (iPhone), let me know.

And also if anybody could tell me how, I want to edit someone kissing me on my cheek in a picture, but I don't know how to do that either.

6.1.4 jailbreak for iphone 5?

I've been looking everywhere for one, and all I get are applications that don't work, or won't download because they ask me for so many surveys.
