Quick ways for teenage girls to tone up and lose weight?

I'm 16, and I'm a junior in high school. My boyfriend is a senior and I'm going to prom with him this school year. I'm not satisfied with my body as of now and I need diet plans so I can lose 40 pounds by April 2014. I'm currently working, and I have so much school work so it's really hard for me to squeeze in time to exercise, although I sometimes use the Nike training app on my iPhone. I just need some diet plans or something to help me out. Please!

ITunes deleted half my songs?

Something weird happened yesterday, so I was adding new songs to my iPhone via iTunes (I didn't buy the songs, just saying).It took a few tries to finally get my phone to download them, but when I did, I noticed that I had less songs than usual. So I checked the number of songs, and it said 115.It used to be 241! I checked on my iPhone library via my computer, and it said on the computer that I still had my 241 songs on my iPhone, even though I don't. How do I get them back on my iPhone?

Why won't my iphone 4 connect to 3G?

I'm on Orange and I checked my data allowance; I've barely used any of my 1GB, so that's not the problem. Wi-Fi works fine. Yet when I try to connect to 3G, no matter where I'm, it won't connect (despite the 3G sign in the top left indicating a good signal). What could be the problem?

How to save an edited photo on an iPhone5?

I edited some photos using an app called, Camera+. They came out great!
But, for some reason, when I put them on my computer they look untouched. I use the app for my photography all the time and post the pictures on Instagram and then save it to my computer after and it turns out the same. But, for these it just isn't saving the filter. What can I do?
I tried screen shotting the edited version, sending it through my e-mail and I'm still getting the un-filtered version.

Why won't my iPhone play certain CD's?

I've got tons of CD's left over from before I ever got a iPod or the like and usually, once moved over to iTunes, they play fine on any device. After the most recent update all of my albums that I have a physical copy for refuse to play and my phone keeps prompting me to put in passwords as if I'm trying to make a purchase. It's getting fairly annoying and I'd enjoy assistance on this topic.
