Can sprint replace my iphone or what?

I cracked my iphone 6 last month, and and dropped it here and there a couple times since then it is kinda badly cracked, so last night it was working normal, then i picked up off my bed and i see these colored lines going through it, i know its messed up from here, then these black spots appeared, so i start getting mad and so i pulled up the screen a bit cause i'm thinking its trash now, i may have damaged it more, but i soon realized maybe this can get fixed. Can it? And i'm on a contract from sprint that still has over a year left, i didn't have phone insurance, is there anything they can do, will they send me a new phone for a renewed contract or what.

None of my plugs are working?

So I thought something was wrong with my charger for my speakers because it stopped working no matter where I plugged it in, and now my laptop just did the same thing. I thought it could be the extension chord by my iPhone charger is plugged in there and it works fine, and that s also where I had the other 2 chargers plugged in. I tried plugging them into different sockets but they ve just stopped working. Does anybody have an explanation for this?

Is it safe to jailbreak iOS 9.0.1?

I've been waiting to jailbreak my iPhone on iOS 9.0.1 because of something called the Boot Loop of Death (BLoD). It's been a while now and I can't find anything about it, has it been fixed?

Will Apple or Sprint charge me?

I have a question. So my iphone won't charge now and i took it to the Sprint store where I purchased it. They told me i could get one for free because I have insurance in it. So here I'm waiting for Sprint to call me to trade my non-working phone. The only problem is my phone is jailbroken but I didn't tell them. Will Apple (or Sprint) find out and charge me? The guys at Sprint already told me my new iPhone is coming in for free. Apple can obviously track my old phone down that I was the owner… But can they charge me? They will have to end up restoring it (because my information is still on there) taking the jailbreak off and they will never know right?

Ho to stop getting messages?

So my little brother has an iPod and I have an iPhone. We share the same Apple ID and that means that I get all of his texts and he gets all of mine. Is there anything I can do to stop this from happening? Sorry it's privacy issues.
