Switching unpaid phone to different line?

I was on my moms phone plan and had an iphone 6. She didn't pay the bill so our phones got disconnected. She refused to pay the bill and late fees so the phones are still out of service. This was last August. Literally a year. So my phone pretty much never got paid off through the contract. Not having a reliable way of communication is becoming a huge problem. So basically my question is, can I switch my phone to a different line/account if its not fully paid off? I can't afford to out right pay the rest off. Its with at&t and thats where I would like to stay. I was hoping I can switch it over to my sisters account and help with the bill.

So here s the story I got into a fight with my brother all the way back in April and then my mom came over to my grandma s house where I live and snatch my iPhone out of my hand now she has refused to give it back and she won't even give it back to my grandmother my mom doesn't own the phone in her name so I'm wondering if I could call the police and see if I could get the phone back then

How do I jailbreak my iPhone 7 plus that is running iOS 10.1?

So I have an iPhone 7 plus running iOS 10.1 and would like to jailbreak it but every YouTube video I see has links that are old and the jailbreak has been removed. Please post links to where I can download the jailbreak. That would really help a lot thanks.

Any idea of using this broken iPhone 6 plus?

I brought this iPhone to Apple Store, and they said they can't fix it, so replacement with $326 only. (Not sure exchange with new or refurbished one)

I can sell this like this for parts, but there may be my passwords those things still there, and I can't access to delete them anymore.

I'm wondering what I should do with this. Any ideas are appreciated!
