Why am i gaining so much weight even though i work out?

Freshman year of highschool i was very skinny 5'0 and 100 pounds but i ate so much. Every one told me that one day i would start gaining weight because of how much i ate. Well sophomore year i was still skinny, still had a fast metabolism and i think i was like 105-110. Junior year came and i was around 115, i mean thats still decent because my body was probably still growing. In the beginning of my senior year (august) i was 117 and still 5'0. I just checked my weight again last month (december) and i was 120. I started getting really upset because i've gained so much weight so i signed up for the gym. Its been one month now and every time i weigh myself i gain like 2 pounds. I'm 130 now. Is that even possible?! How the heck did i gain so much weight. Ever since i signed up for the gym a month ago i started changing the way i eat and i started counting my calories too. I no longer eat over 1200 calories and i just have a pig out day once every 7-10 days. I usually run on the treadmill for 15-20 minutes then i do a 30 minute workout routine on my iphone app. I really don't understand how i gained so much weight! I really want to be 115 again. Is there any diet or anything i can do to make that possible? I'm so upset with myself. Everyone in my family even told me i got fatter because i have a skinny family. My family eats whatever they want so when i eat with them i always try to eat smaller portions and everything but i still don't understand how i gained so much weight so fast. Is there any possible diet or anything i can do to lose this weight as soon as possible. It makes me feel so bad i want to starve myself but i know in the long run thats gonna make me gain more weight. I'm like the fattest one in my family now. I want to be 115 before i go to college. What's the quickest way to lose weight?

If I buy a new stereo for my car with a USB port can it work in any car?

My stereo in my 1998 transport just died. This surprisingly excited me. I just got a new IPhone and I'm constantly installing new music. I'm wondering if I can buy a radio with a USB port and put it in my 98 transport even though my car didn't come with a USB port in the radio. Is this at all possible?

Are there any good live versions of Pumped Up Kicks I can buy?

I have seen some great live performances on Youtube (i.e. Lettermman Live and Terminal 5, and I know a friend has a live version on his iPhone, and I thought he said it's from a PBS show (not ACL).

I generally buy stuff on iTunes and I don't see anything there.

Dropped iPhone 4s, won't turn on?

I dropped my iPhone 4s face down onto my tile floor. The phone won't turn on, even when I plug it into charge. I can't reset it, since the lock screen is broken (has been for months) is there anything I can do, without having to go to the apple store?

Added (1). ********Note: I meant lock button, not lock screen!
