I have an unlocked iPhone 4S and another phone in a contract with AT&T?

I'm not really sure how phone plans work. I want to get service on my iPhone and just forget about the phone I have now. I don't know how long until my contract is over. Do I have to wait until my 2-year contract ends to get service on the iPhone? I don't want to pay a termination fee.

WHY DOES MY MUSIC NOT WORK ON IPHONE ANYMORE

I'm really really really pissed off right now. Like seriously, i almost smashed my iphone to the ground. This is not the first time that this has happened. Previously when i had the iphone 4s, the music worked fine for the first 8 months and then music just stopped working(but worked on one ear).So then luckily a month after that my contract ended so i was able to get the iphone 5. Worked fine for the first month and a half and then randomly, the music stopped working for no reason. And i've tryed other headphones too and it still didn't work. This just happened 20 minutes ago and i'm seriously pissed and i don't have anger issues either. The only thing i can come up with is the lifeproof case i have and had. Because you need to connect your headphones to this headphone jack thing that you need to listen to music. The music on the iphone 4s stopped working 2 weeks after i got the lifeproof case. And not long after i got the case for the 5, it stopped working too. This phone has never been dropped or physically damaged in any way at all. Is there any possible reasons on why the music stopped working and anyway i can get it to work again?

Canceling data plan on iphone?

I have an iphone and my contract ends in February. I really like the iphone, but I'm having some money troubles right now and am trying to cut costs where i can. Would it be weird to call my carrier and ask if they can just cancel the data package on my phone? This way I'll have it for calls and texting and won't have to pay for data. Also, does this mean that all my apps will not work as i just won't be able to use any internet on it?

How to delete songs on iOS 7 for iphone?

I've done everything that has been suggested, such as going to general>music>show all music (off) and it helps and narrows down my songs and allows me to delete some of the songs, but not all of them. Some of the songs just won't delete, and won't even show the Delete option once a swipe. I don't see any difference between these songs that won't delete and others that will.
Is there any other way to delete them? Maybe delete all of my songs on my phone? I want to start fresh
