IPhone 4S: iOS 7, how do I keep apps running in the background?

I like to play fantasica and nfl matchups, but everytime I switch from say fantasica to any other app, or even the home screen, I have to restart the whole app to play it. When I double tap the home button to bring up the background apps that are running, it is still open to what I was doing, but if I open it, it will restart. Can someone please help me?

Is it spoiled for a 14/15year old to get an iPhone?

So i'm turning 15 in january and my parents said they MIGHT buy me an iPhone 5c for my birthday.
i have wanted an iPod for a while now, since i don't have one (and this laptop i'm on right now is not mine so i can't go on youtube) and I NEVER get a chance to listen to music (and even my twin sister has her own ipod).
and i also i have a phone, but it is a flip phone (which i actually honestly don't mind), the only problem is it can't text b/c i don't have he service (also ok w/ me, i'm not into texting), BUT one of my friends keeps texting me even tho i have told her not to,
so having an iPhone will fix both of these problems.also, adding an iphone will get them a deal for the service they pay so the service is not a problem, we will only have to pay for the phone itself.
honestly, i never even asked for an iphone (although i have wanted one), my parents brought up the idea in the first place.
so is it spoiled of me IF they do get me one? I mean everyone my age (and even many kids younger than me) have one and the one my parents are considering is cheaper (5c), but i still always manage to feel guilty if i spend any money, so is it bad to get one for a 15year old?

Added (1). I'm pretty responsible, so i won't break it or lose it (for during pe, i have a lock for my locker which i never forget to put on)

Added (2). And i also usually get good grades
last yr i had all As both semesters, except for one B

Added (3). And i'm not paying for it, but its for my birthday… So is that bad?
and thanks for the answers everyone, very helpful

If you have an iPhone what does this mean?

Ok so my new iPhone 5c is a week old & I'm getting used to it but I have a question. I get that when you text somebody who doesn't have an iPhone they get text messages, but if you text somebody with an iPhone they get an iMessage. But sometimes I will text friends with an iPhone & sometimes it'll go to text messages, not iMessage. Like I texted my friend right now & we were just texting, but then after a while we stopped texting & I asked a question, but that time it went to text message not iMessage & it did that before to like other friends that have an iPhone… What does it mean? Maybe they're phone died or was turned off, or that the message didn't send or what? In confused, please help!

Can I use an AT&T iphone 4s using a Tmobile sim card?

I dropped my phone and broke it, so my friend is giving me her old iphone 4s. Her contract already ended with AT&T, and I heard that once the contract is over, the phone is automatically unlocked and able to be used with any carrier. So my question is whether the phone will work properly with my T mobile sim card and if the phone is unlocked automatically or do I have to jailbreak it myself or bring it to an AT&T location to have it unlocked?
