How come it keeps on increasing?

K so I got the iPhone 5 a few days ago and I signed the contract with 500MB data usage and today I downloaded Roblox(for my little brother) Minecraft (for my little brother) NHL Gamecenter and Hexic Flow, THAT'S IT! And my data usage is 19MB/500MB. After playing for a few minutes, I turn my phone off for 2 hours. When I turn it back on, it's at 79MB/500MB! Why did it increase? I didn't download anything after that!

My iPhone 4S won't sync music?

I lost my first 4s to water damage and when I got my new one I restored it with a back up from a week earlier. Everything seemed fine until I tried to open my music. It says that there's no content.

On iTunes it says that there's 6 gigs or whatever of music and if I click the "on this iPhone" it shows all the songs but they are greyed out.

I have tried syncing it without music then syncing with music. I haw tried closing and reopening iTunes. I have tried restarting the computer with the device still plugged in.

When I take a picture of myself, I look so ugly compared to me in the mirror? - 1

When I film or take a picture of myself on my iPhones (internal) camera and look back at the video or picture I look totally different and I think I look ugly compared to how I look in the mirror. I like the way I look in the mirror and I think I'm a rather good looking lad but when I see these pictures and videos of my I look ugly and I'm like "WHAT?" I hate it and it's made me really self conscious because I want to look like how I look in the mirror!

How do I actually look?

Is how I see my self in the mirror really that different to how I see myself on pictures I take?

Is it just because I'm not used to seeing myself from that angle?

P.s. I take the pictures on my iPhone 5's internal camera (have done on the external as well)
