How to record my iPhone 4 screen?

How can I record my iPhone 4 screen for videos like record going on a game and upload to YouTube.
I can't use a computer and I only want to use my iPhone, is there a way or an app or something where I can record?

Can you record on an iPhone?

Hi! It's so I can record lectures, not the whole thing but most of them so I can take it home and relay what is said? My professors don't really slow down for you haha.

Can I install iOS 7 beta 4 on my iPhone 5?

I'm currently running on iOS beta 3, and I have the option to update OTA (over the air). I can't find any links to the ipsw, so I was thinking I could just update OTA. I'm very hesitant to do this however, as I have heard that Apple will deactivate your phone until iOS 7 is officially released. Does anyone know if it is safe to update OTA?

Which product should I purchase?

I'm planning to save my money and buy a Apple Macbook Air 2013. But I realized how much cheaper iPod 5g's are and how much better they are from 4g. I do not have a job yet as I'm 15 but I get $3 a week from my grandpa and chore money from parents if I do a lot of work around the house. Also I have always saved up my money from birthdays and Christmas too so I now have $365 at home and possibly $100-200 in my bank. I was planning to offer my parents to pay half for the laptop. I want to get it now, before college or university so that when I'm there I can save up for things like a car and my books. I also thought about getting a iPad mini since they are pretty cool and cheaper. But why do I want all these new products?

Laptop: Dell Inspiron 15", running Windows 7
I have now had this laptop for a year and it has been great until…
I got a virus and bugs some how. My laptop is now completely screwed up and may have to be repaired until its too late. My brother had this happen to his laptop and now it won't even turn on, as well as my other brother. So basically here are the problems:
-Firefox has unsafe toolbars and such on it that is hidden so I can't remove
-Google Chrome now has a stupid search bar and I can't get my apps page or Google search bar back and also it refreshes all my tabs randomly
-Internet Explorer is extremely slow and crashes
-Randomly my laptop will stop opening browsers and I will refresh but when I do it literally falls asleep just shutting down so I have to hold power button, WHICH I KNOW ISN'T GOOD but I have been forced to do it over 20 times so now my laptop is Really screwed up
-A random blue screen pops up and "dumps my physical memory to save my laptop from getting damaged" and then the screen won't go away unless I hold the power button
-When my battery is low it literally turns off and makes that weird sound like I just held power button
-Laptop is now kinda slow
-Has many viruses and bugs that I can't get rid of because I would have to buy the programs to do so

SO you get the point and sorry this is so long. My laptop sucks and will soon have to get repaired anyways, which will cost so yeah. Now onto my iPod.

iPod touch 4g, 32 gb (NOT jailbroken)
I've had this iPod for 2 years now and it has gotten pretty messed up.
-Crashes my apps randomly
-Home button barely works, I literally clicked it repeatedly like 20 times just to get there
-My screen dims itself then randomly gets brighter
-Very very slow

I do not have a phone yet, but I'm getting one for my 16 birthday (in May 2014) which I want to be the newest iPhone out. My parents have a HP laptop with Windows 8 that I'm allowed to use and my parents also have a iPad 3 but they're always using it so I can't really use that a lot. My brother is getting iPad mini for his birthday. I realized how much better the iPod 5g is so I wanted to get it and the iPad mini is very cool so I wanted to get that as well. I was originally planning to get Macbook Air but it is so much money and I don't know if my parents will agree or not. Which do I purchase? Should I purchase any at all?
