How to reduce data usage on an iPhone?

Recently made the switch to Apple (iPhone 4) and ever time I look around, I'm receiving a text from Verizon alerting me that I've used 50% of the data or what have you.

A friend suggested that I go into Settings and turn the "Celluar Data" off.

Granted, because I've now gotten the hang of it I'm not fooling around in the Apps Store or constantly using the Internet.

Still, does anyone have suggestions?

Do I have to sell my iPhone 4s Sprint with the SIM card?

So I'm looking to buy a used iPhone 5 for Sprint off of eBay. I've done this before with an SG3 and my iPhone 4s. Both I took and got activated. I didn't even know my 4s had a SIM card because Sprint doesn't use them. When I take it out, however, my 4s says "no sim card" and my service goes away. So it does use it.

Now if I buy an iPhone 5, that doesn't have a SIM card, can I put the one from my 4s into it?

Why does the iPhone 5 have such slow Wi-Fi speeds?

I got a brand new iphone 5 a couple weeks ago and I have noticed that the Wi-Fi speeds are very slow! I began to compare it to my 3rd generation iPod touch. It took the iPhone 5 over 4 minutes and the iPod about 50 seconds to download the same song over Wi-Fi. It's the same for apps, the iPhone 5 is much slower than the iPod. It's so bad that I can't even really watch a video off of YouTube or Netflix on the iPhone 5 because it constantly stops and loads every 6 seconds or so while the iPod is loaded far in advance. The 3G/4g/LTE speeds are ridiculously fast though. Why is it that the Wi-Fi speed is so slow on the iPhone 5 when it is pretty fast on the iPod and every other device on the network?

How to RESET the iPhone 4 when the power button is broken?

(I put "reset" in all caps because I don't need people who don't read the question telling me to go to Accessibility and use an on screen button to make my phone go to lock screen)

My power button broke weeks ago, and the Apple employees told me how to make an on screen power button appear on the screen. Well now I have to reset it to re-install my Wi-Fi, so I need a way to reset (not go to lock screen, reset completely) my phone without the power button.

Is there a way to do this, or am I completely screwed? And don't tell me to get a new phone, because that's out of the question.

IPhone camera makes me look 10x worse (Or maybe I just really look THAT bad?)?

I'll keep it simple. I look fine in the mirror. With my two digital cameras (12.1 MP Sony Cybershot and 14 MP Fujifilm), I look pretty much how I look in the mirror, only reversed. I use flash on those cameras.

The flash on the iPhone makes me looked so washed out and pale and highlights any little spots. The front facing camera. I have no clue what it does, but I feel like it makes me look like I have really fat cheeks. It's pretty devastating how different I look. I'm thinking it's just the crappy indoor lighting? And that maybe flash on high quality cameras = more accurate? I dunno.

But I see people take iPhone selfies, and they look how they look to me. I just wish I looked the same as I imagine on all cameras.

Which is more accurate? Low quality iPhone pics? IPhone pics with flash? My cameras with flash? Mirror? I just wanna know what I look like to everyone else

Added (1). Edit:

@CmoreD I'm not the most attractive guy on the Earth, but I don't think I look THAT bad. (Though my confidence is pretty low.) I dunno, you decide?: image

Either way. That's a crappy iPhone pic with the front facing camera. Basically, the only time I take pics that I like are when I catch myself a little off guard. To be clear, I like that pic. But pics like that don't happen often AT All on the iPhone camera. I like 95% of my pics on the higher quality cameras. Again, I just wanna know what I look like to everyone else.

Can the iPhone 5 get a computer virus?

I was just looking around this website to see if I could watch a movie, and when I went to search it, it opened up 8 tabs and they kept moving and I couldn't stop them until just now (hope that makes sense). I'm scares it could have been a virus. Can iPhone 5 get viruses?

How to transfer amazon MP3 purchases to iPhone iOS6?

I downloaded 4 songs to my iTunes that I purchased on Amazon. They showed up in my library but they didn't sync to my iPhone. So I tried syncing all music, I lost half of my songs. I restored to backup. How can I get these songs on my iPhone with iOS 6? Seriously, Apple's new system really irritates me.
