Having issues with my iPhone 4S?

Okay so on Monday (May 13, 2013) my iPhone 4S stopped working. It would only let me send iMessages and Internet using Wi-Fi, like I'm doing now. Then the next morning I tried calling on my phone and it said it couldn't connect to the Sprint network… So I took it in on Tuesday. They said they just put my number on a different phone in my account. So now I can text and call perfectly fine using Sprint signal but then when I go to Instagram and the safari app… It says "Could not activate cellular data network. You are not subscribed to a cellular data service" but I'm I've texted my friends and they see my texts and they can text me back and I can see it. So I called the woman at Sprint and she told me don't worry you just need to wait 2 hours for your signal to come back then you need to call ##update# to fix the problem. Well I waited and waited and it never came back and when I did the ##update# it failed. So I just want to know if this has happened to anyone else, because I really don't want to go back to Sprint tomorrow because I know they'll reset my phone and I'll lose all my text messages. I don't want to lose them. So does anyone know of a way for me to fix this on my own? I heard I should restore it. Will that fix the problem or do I HAVE to take it back in?

How to Transfer My iPhone Playlists to iTunes?

When I sync, everything normally gets deleted, and iTunes is saying that if I sync it with my phone, 0.55 gigabytes of my phone's memory will be erased, so clearly that's not what I want. Is there any way to sync with the information on my iPhone having preference over my iTunes library, or maybe for iTunes to ask what to overwrite with what instead of automatically deleting everything?

Airport entertainment for a 14year old?

Hi, I'm a fourteen year old girl, who is doing national flying this summer. Hopefully. I just have to get ready. So I'm possibly going to have to fly from California to Denver or Texas. The flight stops in Denver or Texas, and goes to Nebraska. I'm going to be using a pretty large backpack, here's the link: http://www.amazon.com/...00B2P694S/

The backpack has a large compartment inside, with a laptop compartment, I do not own a laptop, :(. But in the laptop compartment is a zipper area small enough to fit index cards and a iPhone. The there's two zippered side pockets on the outside where small things can fit.

Problem is, what should I pack to entertain myself while waiting for the flight, waiting to switch planes, and while i'm on a plane?
(Things I have to entertain myself, :iPhone, ipad mini.)
Any suggestions besides electronics?

Will this work with my speakers?

So I bought these speakers from eBay,
http://www.ebay.com/...0552581662
not knowing I need a receiver to play music from it. I'm now stuck with these and I don't want to spend more money buying a receiver.

Can someone please explain to me if there's another way to play music from these speakers? The only thing I really want to do with these speakers is connect my iPhone to play music from it.
