Video I recorded on my iphone disappeared?

I recorded a video on my iphone(4s) and then went to press the stop recording video but then the screen went to a grey color and a loading sign, kind of how it is when it is in the process of shutting off. I had full battery so I don't know what the problem was. A second later it went back to the home screen.

When I looked at my phone pictures, the video wasn't there. What happened? I thought I pressed the stop recording button but it is not in my files

Asking girl to prom by SnapChat?

I had a thought, what if I were to ask the girl I want to go to prom with by Snapchat.

If you don't know what snapchat is:

"""Real-time picture chatting is finally available on iPhone®!
Snapchat is the fastest way to share a moment with friends.

You control how long your friends can view your message -
simply set the timer up to ten seconds and send.

They'll have that long to view your message and then it disappears forever.
We'll let you know if they take a screenshot!

Build relationships, collect points, and view your best friends.
Snapchat is instantly fun and insanely playful. Show your friends how clever you can be and enjoy the lightness of being!"""

If you think this is a good idea, please give ideas on how it should be done. And if you don't think it's a good idea, please let me know.

Thanks

Added (1). It'd still be in person, but I was thinking I'd be in study hall or something with her… And then send it while we're together.

Unlocking iPhone 5 on contract?

Is it possible to get my iPhone 5 (on contract with Orange) unlocked without breaching contract T&C?

I was thinking about going to a shop in town that unlocks mobiles but what if they check up with Orange to see if I'm on contract?

Can they do that?

Would Orange find out?

And would I even have to tell them I'm on contract in the first place?

Is anyone else experiencing data problems (Virgin Mobile)?

Yesterday, about 30 minutes after I received a text notifying me that Virgin Mobile's terms and conditions had changed, my data stopped working. I can still use my calling minutes and texting, but internet and the apps that use it are nonoperational without data. I get a popup notification on my iPhone 4S when I try to use Safari that says the phone can't access the cellular network. Is anyone else experiencing this or know what's going on?
