Buying used iphone 5s, lost phone?

I'm considering buying a used iphone 5s.
what's worrying me is can the seller on a bad day report lost phone? Because hes the original owner does he hold that power to report that the phone has been stolen? Or when you do a factory reset the new owner would hold this power?

I found an iphone 5 so far it says it is from Canada and was with rogers wireless. Now is there a way to use it in the USA without having to unlock it? If so how? Can it be used with At&t?

Iphone 5s getting warm/hot with minimal usage. Is this normal?

I have had an iphone 5s for a year now. I recently got its screen replaced by apple because it stopped working. Ever since i got the screen replaced, i have noticed that even with browsing safari on Wi-Fi and LTE, it has been getting very warm, enough for me to worry about. Even after refreshing a page about 6 times, the phone heats up. It never becomes scorching hot, and its cool when no apps are running, but whenever i browse the internet, it gets fairly warm, even on Wi-Fi. Does your iphone 5s do this? If this is not normal, how do i fix this?

Can you buy digital comics with a debit card?

Hi. I'm new to the world of debit cards and credit cards and such and such. I'm on my Marvel app on my iPhone 5c and I'm at the part where I'm supposed to choose my payment type. I have the choice of Visa, MasterCard, Amex, Discover, and None. What happens if I choose none? Will it take it from my bank account? Also the billing address is under my mom's name. I take it I just leave it under her name right? I'm 18 and I don't pay for the bills (yet).
